Comparative Analysis of Two Airfoils by CFD Simulation

Abstract

The research work compares two airfoil sections on the basis of computational fluid dynamics (CFD) analysis at different angle of attack to find the stall angle. The main focus is on the simulation of the airflow around the airfoil. The fluid flow simulations are obtained with the FLUENT software package of ANSYS. The model was prepared with the software SOLIDWORKS. The process includes the creation and modeling in SOLIDWORKS and modification of the surface mesh in ANSYS. Further, a way of analyzing the results and some of the outputs of the simulations and analysis has been presented. The CFD simulations were performed on the computational model of an airfoil. The computations were performed for different angle of attacks. It means that the laminar and turbulent flow and several combinations of the angle of attack have been considered.

The research aims to perform a CFD analysis on an aircraft model using FLUENT solver. In the process simulations, meshing techniques, pre-processing and post processing sections and evaluation of a simulation are being learnt. Coefficient of lift and drag were also recorded. These values were also compared by running different simulations with change of input parameter i.e. angle of attack.
