Computational setup Computational Fluid Dynamics (CFD) is going to be a powerful tool for the vehicle aerodynamics because it can provide enormous amount of information as well as high economical efficiency.
Large eddy simulation (LES) is an encouraging solution to the problem because it can reproduce unsteady turbulence characteristics with high accuracy.
It also models the smallest (and most expensive) scales of the solution, rather than resolving them as direct numerical simulation (DNS) does.
The step time for the unsteady simulation was set to 5×10-4s.
The results of the simulations and experiment can be compared in Table 1.
