2D Flow Field Analysis by the Exergetic Method

This paper aims to perform an analysis of the flow field around an airfoil by using the exergetic method. It offers a new way to analyze the aerodynamics based on an energetic reasoning rather than a classical mechanical point of view (used on the far-field method). The objective is to explore the usage of this method as a tool for the aerodynamic assessment of a classical airfoil: the exergetic parameters are related with physical phenomena, and specially used to detect the origin of losses. CFD analyses of a NACA 0012 airfoil at subsonic and transonic conditions were used as test cases to present the concept.
