Complex Aerodynamic Interactions
Propeller wing interactions: CFD is certainly one approach, but is the most efficient? Take a look at this work: https://arc.aiaa.org/doi/full/10.2514/1.C034720
STOVL Aircraft: We explored STOVL aircraft (F35) and their impact to ship crew for fun. One of the things we found is that compressible jet impingement is not only dangerous, it is really quite intriguing. Check out these time-resolved simulations (see more here https://arc.aiaa.org/doi/abs/10.2514/6.2016-4254):
Real-World, Rough Surface Aerodynamics
Roughness is part of the real world. My first job dealt with understanding the aerodynamic effects of debris and bugs had on wind turbine performance through promoting transition to turbulence. Interestingly, the impacts of roughness are much broader and is a topic that CFAL continues to evaluate. Specifically, roughness goes beyond impacting insects and is currently driven by recent trends in advancing ice accretion models as well as additive manufacturing. Check out our work in:
