<div class="section abstract"><div class="htmlview paragraph">SAE Formula Student Car Organization mandates the installation of a 20mm diameter
restrictor between the throttle body and the engine inlet. The primary objective
of this restrictor is to regulate and reduce the mass flow of air into the
engine inlet. To achieve this, a venture nozzle has been selected as the ideal
component, to decrease air pressure while simultaneously increasing velocity
within the intake manifold. This research project focuses on optimizing the
restrictor by strategically adjusting the convergent and diverging angles. To
enhance the restrictor's efficiency, a comprehensive Computational Fluid
Dynamics (CFD) analysis was conducted, exploring a wide range of convergent
angles from 12° to 24° and divergent angles spanning from 4° to 8°. The analysis
was performed using CFD Fluent within the ANSYS Workbench platform. Following an
extensive series of CFD simulations, the optimal angle combination was found to
be a converging angle of 20° combined with a divergent angle of 5°, resulting in
maximum pressure drop and sonic flow. Also, these angles were carefully selected
to maximize airflow velocity, ultimately leading to a significant enhancement in
engine performance.</div></div>
