STUDY AND ANALYSIS OF AN AIRFOIL USING CFD

In this project coefficient of drag and coefficient of lift is obtained with the help of CFD, it is also obtained by experiment which is conducted on wind tunnel. Though both of the methods gives approximate result for the same test section, experimental process have greater cost and quite laborious than that of CFD. Analysis of airfoil over two dimensional subsonic flow at various angle of attack and operating at Reynolds’s number is obtained. The result shown by CFD has closely agreed with experiment result, thus CFD is mature tool to predict the performance of test section at any angle of attack. The objective of the work was to understand the flow pattern over an airfoil and study the stalling effect using CFD. From the present study it is seen that CFD contributes to significant understanding of flow pattern over an airfoil. The following are the important conclusions drawn from the studies carried out in the present work.
