My undergraduate capstone project was to develop a throttle body design for a restricted FSAE engine intake. The existing butterfly throttle body and restrictor were tested using a team built flow bench. The experiment was recreated in CFD, where the model was correlated to within 5% of the pressure drop found using the flow bench at all actuation angles measured. The tuned CFD model was used to simulate alternative throttle designs. The barrel throttle was found to improve flow rate by 6% over the existing butterfly valve and gave a more linear relationship between flow rate and actuation angle. Due to COVID-19 we were unable to test a physical prototype, but were able to adapt and couple our 3D CFD with Ricardo WAVE 1D engine CFD. This showed that the barrel throttle improved power and torque linearity across throttle input to make the car more drive-able. Using lap time simulations and the simulated torque curves, the barrel throttle is predicted to give 6 more competition points at FSAE Michigan.
