Abstract
Computational Fluid Dynamics (CFD) simulation plays a crucial role in analyzing airflow behavior within automotive intake manifolds, significantly impacting engine performance, fuel efficiency, and emission control. This study investigates the airflow characteristics inside intake manifolds using steady-state and transient CFD simulations based on Reynolds-Averaged Navier-Stokes (RANS) equations with turbulence modeling. The simulation focuses on flow velocity distribution, pressure drop, and turbulence intensity within various manifold geometries under different operating conditions. Results show that optimized manifold design can improve air charge uniformity and reduce pressure losses, which ultimately enhance volumetric efficiency. The study validates CFD as a reliable tool for intake manifold design optimization in internal combustion engines.
