Abstract

Nowadays, the automobile industry is increasingly developing, along with the requirements of reducing fuel consumption, the design of cars with good aerodynamic shape is of interest to many countries in the world. Therefore, reducing aerodynamic drag is one of the issues that car designers put first. The method of simulating fluid flow through the car uses the finite volume method for unstructured mesh, using Fluent software based on the Reynolds Navier - Stokes average equation and the standard k - ε turbulence model. The accuracy of the problem depends on the number of grid points and the computer resources. The problem is solved by the sequential solution method. The simulation results are shown in intuitive graphics, which are the pressure and velocity distribution fields.
