Epsilon: An Open Source Tool for Exergy-Based Aerodynamic Analysis

This paper presents the open source code called “Epsilon”. It is a tool suited for the aerodynamic analysis of CFD and wind tunnel data by using the exergy method. Other methods are also provided (near-field, far-field, Lamb vector). The architecture of the code is presented as well as a qualitative description of the analysis capabilities provided by the tool. Some reference test cases are presented and an accuracy assessment of the exergy analysis is performed. The software is released to the public along with this conference paper.
