Flow Analysis of Intake Manifold Using Computational Fluid Dynamics

The main element of the air intake system is an manifold. These are components which control flow value that will be used in combustion chamber. Thisstudyaimsto analyse velocity distribution all runners and to compare design manifold previous study. Simulations performed on two types Design 1, inlet end located next regulator chamber whilst for 2, inthe middle Intake parameters such as distribution, unevenness pressure losses along runner determine better performance. From results, velocity,and these twotypes determined. Compared with study, difference 0.05%. This showed simulation result obtained this study accordance Next, percentage between 1 approximately 4%. Furthermore, 2 0.3% achieved range acceptable values 2500Pa 3000Pa. results evenness each shows met criteria exhibited best improvement compared 2% improvement.
