Improving the Flow-Through Section of the Intercooler of a Racing Car Using Numerical Simulation

To participate in international motorsport competitions Formula SAE, BMSTU student design team developed a racing car with a Yamaha WR450F internal combustion engine. The engine was equipped with a turbocharger and an intercooler to increase the engine power. Numerical simulation of the spatial flow was performed using the ANSYS software for several variants of the flow-through section of the intercooler. Based on the simulation results, the flow-through section that provided a reduction in weight of the intercooler and a significant decrease in the resistance of the cooled air flow was chosen. Using this design, it is possible to increase the engine power and, as a result, improve all the technical characteristics of the racing car. For the mathematical description of the flow, a system of viscous gas equations in the Navier-Stokes form was applied. The processes of turbulent mixing were taken into account through using both the k–ε and the k–ς–f models.
