The exergy method is a powerful tool for aerodynamic analysis and drag prediction. However, its formulation still requires further improvements in order to obtain a useful drag breakdown for the analysis of wind tunnel data (like the far-field methods). The far-field drag breakdown is achieved by using a velocity decomposition technique but the related formulation is not well suited for the exergy method. Thus, the main objective of this work is to develop a new velocity decomposition suited for the exergy analysis and to propose a related exergy-based drag breakdown formulation for wind tunnel applications.
