Aerodynamics Characteristics Of Elongated Vehicles Under The Effect Of CrosswindAhmad Muzakkir Bin WahabA11MJ0003 Dr. Mohamed Sukri bin Mat Ali

IntroductionCrosswind is any wind that has a perpendicular component to the direction of travel. Crosswind as the secondary effect of the move on the road in the open areas represents a significant risk for vehicles. The situation occurs when the impact of crosswinds causes the vehicle to deviate from a straight line or simply rolls over.

Objective To study the characteristics of flow over an elongated vehicle under the effect of crosswinds.To study the influence of the elongated vehicle geometry on the flow structure over the elongated vehicle

Methodology Simulations will be done using OpenFOAM, an open source CFD softwareAnalysis will be done using Matlab

Expected resultsTo have a better knowledge about the aerodynamic behavior of elongated vehicles.To gather data for aerodynamic characteristics and identify the most suitable geometry for elongated vehicles.

Conclusion I hope that I can understand the characteristics of flow over an elongated vehicle under the effect of crosswinds.To understand the influence of the elongated vehicle geometry on the flow structure over the elongated vehicle
