STUDY OF AERODYNAMIC WAKE ANALYSIS OF SUV CARS FOR IMPROVING FUEL CONSUMPTION

SUV cars are known to be some of the most fuel-inefficient vehicles on the road. This is due in part to their large size and shape, which create a lot of aerodynamic drag. The wake region behind an SUV car is particularly turbulent, which further increases drag. The aim of this study of aerodynamic wake analysis of SUV cars for improving fuel consumption is to identify and quantify the factors that contribute to aerodynamic drag in SUV cars, and to develop strategies for reducing drag and improving fuel economy. Identify the factors that contribute to aerodynamic drag in SUV cars. This will involve understanding the flow dynamics of the wake region behind SUV cars and identifying the key features of the wake that contribute to drag. Develop strategies for reducing the size and strength of the wake. This will involve developing methods for modifying the shape of the SUV car or the flow around it in order to reduce drag. Assess the impact of wake reduction on fuel economy. This will involve conducting wind tunnel tests or CFD simulations to determine how changes in the wake affect the overall drag of the SUV car. This study researches the streamlined wake of SUV vehicles to distinguish amazing open doors for diminishing drag. Wind tunnel tests and CFD analysis are utilized to examine the stream designs around and behind an assortment of SUV models. The outcomes show that the streamlined wake of SUV vehicles is described by two enormous vortices. These incorporate diminishing the detachment point at the back of the vehicle, streamlining the backside of the vehicle, and utilizing streamlined gadgets like spoilers and diffusers. In this comparative study we designed and developed a prototype of a conventional SUV body with square back to analyse the actual drag and wake behind the vehicle using CFD analysis and Wind Tunnel test. After performing all the tests for conventional SUV, results are documented to compare the results determined with modified body.
