Computational Simulation of Ahmed Body with Varying Nose radius, Ground height & Rear Slant angle
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
The CFD analysis is used to analyze the complex flow behavior, flow separation and drag around the body. For this study, a simplified Ahmed body is considered as a test body which is commonly used in industry. Ahmed body consist of round nose part at front , a movable slant plane at rear end and a rectangular box , which connect rear and front part. The analysis is carried out by varying the slant angle at 250 and 350 angles. Also at each rear slant angle, the two separate cases have been studied by changing the nose radius i.e. R100 mm and R120 mm. Further modification on ground clearance from 50mm to 60mm have been carried out .The results are compared for all the cases in the form of drag coefficient and flow field. Air is assumed as an external medium and the inlet velocity of air is taken as 40m/s. K-ε turbulent model is used in order to account the turbulent flow around the Ahmed body.
