Formula SAE (FSAE) rules require an intake system restrictor be placed between the throttle body and the engine. The rules specify a maximum throat diameter for gas engines, so the intake restrictor serves as a design constraint for the competition by reducing the mass flow to the engine, thereby limiting the maximum power produced. CFD can help optimize the design for an intake restrictor to get more power out of the engine so teams can go faster and score better at the competition.
Air Intake Restrictor GeometryIn the video demonstration, students will learn how to perform a CFD analysis on an FSAE intake restrictor using Ansys Discovery. In part 1, you will learn how to create geometry for an FSAE intake restrictor. You will also become familiar with setting up and moving through the fluid simulation workflow in Discovery’s Explore mode. In part 2, you will use Discovery’s Refine mode to produce high-fidelity simulations. You will learn how to optimize and validate fluid results of a FSAE intake restrictor.
