Design and CFD Analysis of The Intake Manifold for the Suzuki G13bb Engine
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
This paper deals with the improvement of the performance and to achieve the even distribution of flow at each cylinders, to select the best turbulence model for the analysis of intake manifold using computational fluid dynamics, to achieve the maximum mass flow rate through the runners, to maintain the equal pressure throughout the plenum, to propagate back the higher pressure column of air to intake port within the duration of the intake valve’s closure. To achieve the even flow of distribution and improve the volumetric efficiency, author divided his analysis into three different parts. In each part, a different iteration of inlet manifold used in Maruti Gypsy’s G13BB engine are used. In this analysis plenum size is kept constant to show the effects of shape of runners on output. Dividing the work into three different parts provide the greater refinement in result. Runner shape is determined by the operating conditions of the engine assembly in which the inlet manifold is used. The intake runner diameter influences the point at which peak power is reached while the intake runner length will influence the amount of power available at high and low RPM. To find the best results, author perform the experiments in Ansys Fluent for possible designs and find the effect of curved and helical shape runners were providing higher volumetric efficiency and even flow of distribution to each cylinder. For designing final intake manifold author select best design from all three parts and perform the experiment using computational fluid dynamics software Ansys Fluent.
