TY - BOOK AU - Saravanan Vijayan @ Ganasen TI - Design optimization in air intake system of 1.6 l enigne by adding guide vanes SN - THE0006336(Local) PY - 2009/// CY - Kuantan, Pahang PB - UMP KW - Spark ignition engines KW - Automobiles KW - Fuel systems N1 - Project paper (Bachelor of Mechanical Engineering with Automotive Engineering) -- Universiti Malaysia Pahang - 2009; Bibliography : p. 76-78 N2 - This thesis presents a research and analysis of model AIS optimization how air is ingested and air wake, pressure losses or separation flow occurs is developed in the air intake system on a vehicle driving at various velocity with using turning vane or guide vane in the air intake system are assumed that could decrease loss. This analysis can be done in Computational Fluid Dynamic (CFD) analysis using a model setup with appropriate speed of the Proton Waja 1.6 varies from maximum speed to minimum speed where it will be virtual analysis for the Proton Waja Car. This will help to view the sucking process of air as car in normal speed. With help of the graph generation by the CFD results the air velocity flow and the losses in the system can be calculated with or without using turning vane. For this flow analysis CosmosFlow 2008 will be used to indicate the system pressure drop and type of flow disturb. With help of Computational Fluid Dynamic (CFD) the study how air wake or Separated Flow progresses in the air intake system this is also an reverse engineering method where the model will be done in SolidWorks software and analysis will be done in CFD. Air intake system and filter play major role in getting good quality air into automobile engine. It improves the combustion efficiency and also reduces air pollution. This paper focuses on optimizing the geometry of an intake system in automobile industry to reduce the pressure drop and enhance the filter utilization area. 3D viscous CFD analysis was carried out for an existing model to understand the flow behavior through the intake system, air intake geometry and filter media duct ER -
