International Research Journal of Engineering and Technology (IRJET) e-ISSN: 2395 -0056 Volume: 04 Issue: 05 | May -2017 www.irjet.net p-ISSN: 2395-0072 A Review on CFD Analysis of Drag Reduction of a Generic Sedan and Hatchback Shashi Kant1,Desh Deepak Srivastava2,Rishabh Shanker3,Raj Kunwar Singh4,Aviral Sachan5 1M. Tech., Mechanical Engineering, Noida Institute of Engineering & Technology, Greater Noida, Uttar Pradesh, India 2,3,4,5B.Tech., Mechanical Engineering, IMS Engineering College, Ghaziabad, Uttar Pradesh, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - In today’s world, Automobile industries are about 10% to 20% for operating electrical appliances and working on increasing the fuel efficiency of vehicle alongwith 50% to 60% to overcome the drag force. So reducing of maintaining the stability at high speed. Advanced tools like aerodynamic drag has become the primary concern in Ansys-(Fluent) may be used for analysis and hence reducing vehicle aerodynamics great efforts in research have been the drag force , increasing the stability and fuel efficiency. This employed for better fuel economy and performance of review attempts to compare the effect of drag forces on sedan aircraft and road vehicles due to market competition.[5] car on applying different types of spoilers, vortex generators Study of flow around solid objects of various shapes is called and also compare the sedan’s car drag force with that of an external aerodynamics. Examples of external hatchback type car. aerodynamics are evaluating the lift and drag on an airplane, Key Words: Fluent, Drag Coefficient, Spoilers, the shock waves that form in front of the nose of a rocket, or Aerodynamics, Sedan & Hatchback the flow of air over a wind turbine blade are examples of external aerodynamics.
