Development of Numerical Simulation Method of Flow Around Automobile Using Meshfree Method

A CFD simulation solver using a Meshfree method, free of complicated grid generation, has been developed. The characteristic of this method is to use a moving least squares interpolation, in order to improve analysis accuracy of a virtual boundary method. The simulation results show good agreement with wind tunnel experiments. Furthermore, this method was applied to the numerical simulation of flow around a structure which was moving or deforming. As a result, it is found that this method is effective and has a great future in Fluid-Structure Interaction.
