THE EVALUATION OF MESH CHARACTERISTICS OF THE CAR MODELING AND SIMULATION USING CFD ANALYSIS
Keywords:CFD, Meshing, Car Modelling, Simulation, Evaluation.
AbstractIn a car CFD simulation, different types of mesh could change the output of the simulation and may differ with the results gathered using wind tunnel experiment. Therefore, adjusting and getting the best mesh for the simulated car model is an important step in a CFD simulation. This study investigated the effect of the different number of elements on a saloon car CFD simulation. The elements themselves have a similar mesh quality, but the number of elements ranged from just over a couple hundred thousand to over 3 million elements. The results show that with this number of mesh, the accuracy did not increase significantly even though the elements multiplied in amount. It is suggested that simulation with higher number of elements might be the best choice if the facilities are supportive. It is also shown that the lower number of elements could be an alternative because the accuracy is sufficient.
