F1technical take a look at the aerodynamics of an F1 car designed to the 2021 regulations as compared to the modified Perrin F1 model used in previous studies. Getting the boring stuff out of the way, this study was performed using Ansys CFX with a RANS solver and a k-omegaSST turbulence model. The car was set to a ride height of 5mm as measured on the reference plane at the front axle and 93mm at the rear axle (a rake angle of 1.4°). The wind speed was set at 50m/s (180km/hr) and for this first baseline case no sideslip was set, though future runs will feature a small cross-wind angle or curved flow to imitate a cornering manoeuvre. The mesh contained approximately 32 million cells for...
