Abstract
The purpose of this paper is to present an exergetic approach which provides a good complement to classical drag computation in order to assess aerodynamical performances. Unlike drag methods and, on a more general level, unlike any force-based analysis, no distinction between drag and thrust is required. Thus the exergy approach can be applied to a great variety of novel configurations for which the propulsion system is highly integrated within the airframe such as configurations with boundary layer ingestion for example. It also provides information about thermal effects which can not be extracted from drag computation. This paper aims at giving an insight into the exergetic approach and analysing its sensibilities to numerical parameters such as CFD computation convergence and mesh refinement, an assessment which is important as a basis for the improvement of the method’s accuracy.
