Abstract

Airfoil is the shape of a wing, which plays a pivotal role in generating adequate lift to adjust the heaviness of the aircraft body and to help it fly. Simulation for NACA 2412 airfoil was performed using the available Computational Fluid Dynamics techniques. The model of the NACA 2412 airfoil was prepared using the coordinates obtained from the University of Illinois’ airfoil database. Popular CAE software Ansys (CFX) was used in this case. Firstly, the coordinates were imported to Ansys geometry modeler, and then CFX (Fluid Flow) was used to generate mesh and conduct the experimentation. At the end of model & mesh generation, simulation was done to observe the effect of flow on the said airfoil model at a high Reynolds number and the variation in angle of attack with respect to the aerodynamic forces acting on it. To conduct the entire experiment, I did not opt for physical set up as the physical model has to be placed inside a wind tunnel, and this process is quite laborious, time consuming and expensive too at the same time. Moreover, the wind tunnel experiments are subjected to the accuracy of the developed model. With the advancement of high configured computers and computational methods, the flow behaviors of the fluid and its effect can be accurately analyzed.
