A Numerical Study of Turbulent Flows Around a NASA 0012 Profile for Wind Turbines Using the K E Model
Abstract
Currently, the development of renewable energy sources is one of the most important issues. An environmentally friendly and cheap energy is wind energy. Therefore, it is necessary to study turbulent flows around aerodynamically shaped profiles when creating new models of wind turbines. It is impossible or too expensive to study these currents by experiment. Therefore, it is appropriate to model it using modern package programs. This article presents a study of a turbulence model in subsonic flow around a NACA0012 airfoil with angles of attack from 0 to 20 degrees. For the numerical implementation of the turbulence equations, the finite element method was used, implemented using the software package Comsol Multiphysics. The k-e model was used to determine the turbulence. The results obtained were compared with experimental data and showed good agreement between them, which confirms the adequacy of the proposed turbulence model. The main aspects of the research methodology are discussed, including modeling parameters and analysis of the data obtained. This study contributes to the understanding of turbulent flow around airfoils and may be useful for developing more accurate engineering models.
