Numerical investigations of the exergy balance method for aerodynamic performance evaluation

Extension of the Exergy Balance to Rotating Frames of Reference : Application to a Propeller Configuration

“…wasted in terms of potential for thrust production) and the anergy generated, corresponding to the exergy destroyed by irreversible phenomena. This formulation was successfully applied to conventional and disruptive configurations of aircraft [5], studied and improved numerically [6] over the last years.…”

“…For this reason, H * and S * do not correspond to a correction but rather to an estimation of numerical errors in the analysis. Specific strategies have been developed in order to quantify and isolate these numerical errors, in particular the purely numerical anergy generation (also called spurious anergy) [6].…”

Assessment of Exergy Analysis of CFD Simulations for the Evaluation of Aero-Thermo-Propulsive Performance of Aerial Vehicles

“…As for the NACA0012 test case, the accuracy of the FFX decomposition with respect to CFD convergence has been studied on meshes L2 to L4. The figure (9) only shows the result for mesh L3 but the terms have a very similar behaviour on all three meshes. The total anergy term provides the fastest convergence and is even faster than the far-field drag term.…”

“…This paper gives attention to theoretical and numerical aspects of exergy analysis from solutions of the Reynolds-Averaged Navier-Stokes equations. Note that previous work has been presented at the AIAA AVIATION Forum by Petropoulos [9]. It was then a first attempt at analysing numerical behavior of our postprocessing tool and it proposed hints to find way to reduce numerical errors.…”

An Overview of ONERA Research Activities Related to Drag Analysis and Breakdown

“…Multiple studies have been conducted to evaluate this new exergy balance formulation on a wide range of configurations [56][57][58][59]. More recent investigations have also focused on the understanding and quantification of the influence of numerical effects, which is essential for the application of the method to the analysis of numerical solutions in an industrial scale [60,61].…”
