Investigação numérica de escoamentos subsônico e transônico ao redor do perfil NACA0012

Abstract

Many areas of engineering need the study of the physical phenomenon where fluid flow occurs at high speed. Since the analytical solutions are not enough to solve most of the practical problems, especially in complex geometries, and the experimental analyzes are often expensive, numerical analysis becomes a good alternative for these studies. This work aims to analyze numerically the arfoil NACA0012 in subsonic and transonic flows through the code HYNE2D and to perform an analysis of the results obtained to complement the literature on the subject. The work was done in laminar flow, compressible, isentropic and adopting the assumption that the fluid is a perfect and continuous gas. The code used uses the finite volume method in unstructured meshes. The convective flux is calculated by the methods AUSMPW and ROE, the diffusive is calculated by the Green-Gauss method. The time advance is calculated explicitly by the Runge-Kutta method.
