This paper aims to provide a prediction method for the transverse exergy of the wing’s trailing vortices. It relates the transverse exergy at each point of the entire downstream survey plane to the vorticity inside the wake. This allows reducing the survey area to the wake region only, leading to a useful expression for the calculation of the transverse exergy from wind tunnel measurements. The proposed equation offers a significant improvement respect to the Maskell method especially at high-angle of attack condition. CFD analyses of a NACA 0012 rectangular wing at subsonic and transonic conditions were used as test cases to present the concept.
