Recently, a number of works related to film cooling was reported both experiments and computational fluid dynamic (CFD) simulations have been investigated.
As the CFD developed, the numerical tools give another way to analysis the film cooling.

In this paper, the numerical simulation analysis of jlu fsae racing car aerodynamic character based on star-ccm+ was introduced.
Numerical Simulation Overview Model of Simulation.
Based on the star-ccm+ software, we do a external flow field numerical simulation of the jlu fsae car.
In this paper, by comparing the simulation results of the four kinds of condition for the car flow field numerical simulation, we search for the appropriate boundary condition setting and study the influence to simulation results by the rotation of the wheels.

For example, in today’s automotive industry, state-of-the-art software tools are used with simulation techniques such as Finite Element Methods (FEM), Computational Fluid Dynamics (CFD), Multibody Simulation (MBS), Crash Simulations and Topology Optimization techniques, all of which reduce the overall development time and improve the accuracy and safety.
Alongside this, CFD simulations are also used to compute different wind loads on the structure.

For this simulation, the car is assumed to be travelling at 25m/s (90km/hr).
Table 1 shows the simulation result of drag coefficient of each model with different wind turbine system position.
This is proven by this simulation where the drag coefficient of a car without the wind turbine is 0.39.
