Space Advantage Provided by DeLaval Nozzle and Bell Nozzle over Venturi

Abstract:-The FSAE guidelines state that it is mandatory for each and every car participating in the said event to have a single circular 20mm restrictor in the intake system. All the air flowing to the engine must pass through this restrictor. Conventionally, a Venturi Nozzle is used as a restrictor. In our research, we have proposed two Nozzles: De-Laval Nozzle and Bell Nozzle as an alternative to the Venturi Nozzle. After numerous CFD Simulations; we have inferred that the results of the De-Laval Nozzle and Bell Nozzle are similar to the Venturi Nozzle. Along with providing similar results, the two nozzles provide a space saving of 6.86% over the Venturi Nozzle. The data was gathered from SolidWorks Flow Simulation 2014.
