Computational Analysis of Fluid Behaviour Around Airfoil with Navier-Stokes Equation

Abstract

A study of the development models and shapes of aircrafts component that undergo refinement process over time, must go through the analysis phase. The analysis can be solved by computation method which is supported by the development of numerical method. One important component of aircraft is airfoil. Airfoil is a part that influences the lifting force on the wing of the aircraft. Therefore, in this study should be conducted a study of three different forms of airfoil, about the behaviour of the fluid flow around it, numerically. The approach to fluid flow behaviour can be done using the Navier-Stokes equation. The airflow velocity around the airfoil is the fluid flow behaviour to be analysed, so the numerical solution can be obtained through Finite Element Method (FEM), then it is simulated with COMSOL Multiphysics 5.2a software. Thus, the simulation results will show the interrelations between the angle of attack (α) which varies with the maximum velocity distribution on each airfoil surface, and can be seen the most stable maximum velocity distribution among the three airfoil forms.
