SPACE OPTIMIZATION THROUGH THE USE OF DE-LAVAL NOZZLE AND BELL NOZZLE AND ITS THEORY

摘要

The FSAE (Formula SAE) 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. The restrictor design through appropriate selection of Nozzle type has been carried out in this work. This criterion for Nozzle selection is also discussed. 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.
