Secrets of Citrus Micro-Jets

Among the many sub-disciplines of physics are quantum mechanics, cosmology and the physics of fruit.

It’s not a field that universities or learned societies recognize, but it fits the investigation of how reservoirs in the skin of citrus fruit burst and shoot out micro-jets of aromatic oil at more than 30 feet per second.

Andrew Dickerson and his colleagues at the University of Central Florida in Orlando investigated the phenomenon purely out of curiosity. Anyone who has handled a lemon or a navel orange may have noticed that when the skin is bent, a little bit of oil comes out in a tiny spritz. These are to be distinguished from the wayward squirts of juice that can hit a dinner companion when you are trying to add a dash of lemon to your sole.

The scientists used high-speed videography to track how the process works and found sacs of oil in the relatively soft part of the skin just below the more rigid outer layer. They used pliers to bend skin of several citrus fruits and found that at a certain point, the stress on the skin causes a break and the oil reservoir empties in a burst.

Micro-jets are found in other plants and in animals as well, such as spitting termites and spiders. Why citrus plants show this action when the skin is bent in an extreme way isn’t known, although the oils are toxic to some insects, plants, and microbes. The micro-jet phenomenon is the reason that bartenders twist an orange or lemon peel to release the flavor, but that is not likely to have played a part in their evolution.

The experiments, reported in the Proceedings of the National Academy of Sciences, may be helpful in fields like medicine or commercial printing or even in devising monitors for stress in bridges. For instance, a micro-jet sensor might indicate when too much stress is put on part of a bridge, bursting and spraying a dye.

That’s speculation. Dr. Dickerson said that he had undertaken the investigation because of conversations eight years ago with David Hu of Georgia Tech when Dr. Dickerson was an undergraduate working in Dr. Hu’s lab.

And one of the things he takes away from the findings, after viewing the high-speed videos, is that everyday life is filled with hidden marvels, “ubiquitous examples of natural beauty.”

“How many times have you peeled an orange?” he asked. “How many other things in life pass us by and we don’t appreciate them?”

SAE Formula and Baja Competition Highlights

The MAE Department would like to highlight the SAE Formula and BAJA team’s performance in their competitions this year.

The Formula team competed at the Michigan International Speedway, making it into the Design finals for the first time in the team’s history and placing ninth. Despite issues with the weather, the Formula team placed twenty-fifth in the Autocross event and finished twelfth for the Cost event. However, due to an electric throttle body failure, the team failed to complete the highest-scored event, the Endurance event, and placed fifty-fourth out of one-hundred twenty as a result.

The BAJA team competed in two competitions: Maryland and Kansas. In Maryland, the BAJA had various successes: Placing in the top five in the Cost Hill Climb, top fifteen in Acceleration and Maneuverability, and a top ten finish in Design, a first in a long time for the BAJA team. Despite failures in the Endurance event, the team finished twenty-first out of ninety-four teams. The BAJA team, also, had success in Kansas placing fourth in Cost, tenth in the Endurance, and top twenty in Design and Sales managing to place ninth out of ninety-five teams.

Congratulations on behalf of the MAE department to the SAE Formula and BAJA team for their performance in their competitions!

Seminar Series: Structural Architectures for Giant Coilable Spacecraft

The UCF Mechanical and Aerospace Engineering Department continues the Seminar Series by welcoming Dr. Sergio Pellegrino on Friday, April 20th from 1:30-2:30 PM in ENGR II, Room 103. Dr. Pellegrino will present his topic “Structural Architectures for Giant Coilable Spacecraft”.

(Abstract) New kinds of spacecraft, with specifically optimized architectures, may be the best answer to society’s need for cost-efficient space-based infrastructure. Instead of the traditional spacecraft bus, mostly filled with electronic systems, and attached to large deployable appendages that provide power, communication and other functions, alternative structural architectures can provide more efficient, integrated solutions.

In this talk, I will focus on a novel spacecraft architecture, currently under development by the Space Solar Power Project at Caltech, that has the specific purpose of collecting sunlight, converting it into RF power, and radiating it in a narrow beam. This architecture was inspired by kirigami, the extension of Japanese paper-folding that also includes cutting of the paper. Its realization involves thin shell structures that are folded into a tight nested coil. Fundamental research in the mechanics of coiling and uncoiling of thin shells, and the analysis of stress concentrations in coiled thin shell structures with complex geometries will be presented.

Dr. Sergio Pellegrino is Joyce and Kent Kresa Professor of Aeronautics and Civil Engineering at the California Institute of Technology, Senior Research Scientist at the Jet Propulsion Laboratory, and Co-Director of the Space Solar Power Project. He received a Laurea in Civil Engineering from the University of Naples and a Ph.D. in Structural Mechanics from the University of Cambridge. He was on the faculty at the University of Cambridge prior to joining Caltech. Dr. Pellegrino is a Fellow of the Royal Academy of Engineering, a Fellow of AIAA and a Chartered Structural Engineer. He is currently the President of the International Association for Shell and Spatial Structures (IASS) and the founding chair of the AIAA Spacecraft Structures Technical Committee. Dr. Pellegrino has authored over 300 technical publications, and received several awards including ICE James Watt Medal, AIAA Gossamer Spacecraft Forum Best Paper Award, IASS Tsuboi Award, ASME/Boeing Best Paper Award, and ASME Mechanisms and Robotics Committee Best Paper Award, Pioneers’ Award from the University of Surrey, and NASA Robert H. Goddard Exceptional Achievement Team Awards. His area of research is the mechanics of lightweight structures, focusing on packaging, deployment, shape control and stability, novel concepts for future space telescopes, spacecraft antennas, and space-based solar power systems.

Seminar Series: Mechanical Suppression of Pathological Tremor via External Artificial Muscles

The UCF Mechanical and Aerospace Engineering Department continues the Seminar Series by welcoming Mr. Chris Kelley on Friday, April 6th from 1:30-2:30 PM in ENGR II, Room 103. Mr. Kelley will present his topic “Mechanical Suppression of Pathological Tremor via External Artificial Muscles”.

(Abstract) Pathological tremor is the involuntary, approximately rhythmic motion of body parts that stems from a nervous system disorder. These involuntary motions decrease the quality of life of those afflicted. Typical treatments such as medications and surgery are not always effective and have inherent risks and side effects. Despite its neurological origin, the ultimate output of tremor is a mechanical motion; therefore, it is possible to mechanically suppress tremor. Mechanical tremor suppression has the potential for perfect cancellation of tremor with minimal risk.

However, two key factors affect the performance and feasibility of mechanical tremor suppression: the device must avoid influence on voluntary motion and be compatible with the human body. To address the latter, this study proposes the use of soft actuators for tremor suppression; specifically, dielectric elastomer stack actuators are an intriguing solution since they have similar mechanical properties as human muscle. This study employs an agonist-antagonist actuator pair to target suppression at a single joint. This work develops two tremor suppression controllers that have tradeoffs among robustness, control effort, and their effect on voluntary motion. Numerical and analytical simulations demonstrate the potential of a dielectric-elastomer-based tremor suppression system. The proposed system offers significant theoretical improvements in user comfort, device profile, and scalability—all factors that currently prohibit the clinical use of mechanical tremor suppression.

Mr. Chris Kelley is a Doctoral Candidate at UCF working in the Structural Dynamics and Adaptive Structures Lab. Chris received his BS in Mechanical Engineering from the University of Florida in 2013 and his MS in Mechanical Engineering from UCF in 2016. He has worked on several research projects at UCF, including piezoelectric-based vibration reduction and modeling of composite laminate plates with embedded piezoelectric material. Chris’ interest in the movement of the human body coupled with his background in smart materials research led to his doctoral research project: mechanical tremor suppression using soft actuators. So far, his work has produced four conference presentations and three journal publications. Overall, Chris’ research interests include biomechanics, controls, and dynamics.

Seminar Series: Multiphysics and Multiscale Simulation of Materials Processing by Meshless Methods

UCF Mechanical and Aerospace Engineering Department continues its Seminar Series by welcoming Dr. Božidar Šarler on Friday, March 9rd from 1:30-2:20PM in ENG II, Room 103. Dr. Šarler will present his topic “Multiphysics and Multiscale Simulation of Materials Processing by Meshless Methods”.

(Abstract) The structure of a novel meshless solution procedure for calculation of solid and fluid mechanics problems, coupled with the electromagnetic fields, is presented. The multiphysics solution framework is coupled to multiple scales by incorporating the cellular automata and the phase-field concepts of microstructure evolution. The solution procedure is defined on a set of nodes which can be non-uniformly distributed. The domain and boundary of interest are divided into overlapping influence areas. On each of them, the fields are represented by the collocation with radial basis functions or by least squares approximation on a related sub-set of nodes present in the influence area. In the case of cellular automata modelling, the transition rules are defined for the states of the set of nodes in the influence area. The timestepping is performed in an explicit way. All governing equations are solved in their strong form, i.e no integrations are performed. The polygonisation is not present. The large deformation and growth problems are handled by node redistribution and activation of additional nodes, respectively. The solution procedure can be easily and efficiently adapted in node redistribution and/or refinement sense, which is of utmost importance when coping with fields exhibiting sharp gradients such as phase field variable or enthalpy in phase-change problems. Step by step benchmarking of the method is represented, followed by some large scale industrial examples such as the grain structure formation in continuous casting of steel, turbulence modelling with solidification, electromagnetic casting of aluminium alloys, etc. The results of the new approach are compared with the analytical solutions, well documented bench-mark solutions and commercial packages. The method is extremely simple to code and accurate, allowing straightforward parallelization. Besides this, the inclusion of complicated physics can be performed in a straightforward manner, reducing the development time. The coding in 2D or 3D is almost identical. Applications to several large scale industrial problems are shown, particularly in the field of thermomechanical processing of steel and aluminum alloys. A selection of 20 related representative references of the team is given.

Professor Božidar Šarler is Chair of Department of Fluid Dynamics and Thermodynamics at the Faculty of Mechanical Engineering, University of Ljubljana. He is also Head of Laboratory for Simulation of Materials and Processes at the Institute of Metals and Technology in Ljubljana, Slovenia. He has worked outside Slovenia cumulative for more than four years as a researcher at Centre of Nuclear Studies, Saclay; University Erlangen-Nuremberg, Nuremberg; Argonne National Laboratories, Chicago and as a visiting professor at the University of Nevada, Las Vegas; University of Pierre and Marie Curie, Paris; Polish Academy of Sciences, Warsaw and University of Parthenope, Naples.
