Abstract

In this paper, CFD is used to perform analyses of 3 different airfoils at varied angles of attack. The objective is to determine a suitable CFD model and find a single validated simulation setting applicable for different airfoils. The pressure coefficient around an airfoil is analyzed. A single Reynolds number condition is assigned for testing of each airfoil over different angles of attack. The CFD results are compared with experimental and XFOIL data. The solver used is the commercially available ANSYS v16.0 CFX. From this study the following results are derived: It is found that the simulation results closely match experimental results at Reynolds number in the range of 3 million. At low Reynolds number, the CFD approach struggles to reach the higher values of pressure coefficient achieved experimentally. It is also found that XFOIL provided better results compared to CFD and also converged at a faster rate. The above results are discussed in this paper.
