Aerodynamic force by Lamb vector integrals in unsteady compressible flows

What is it about?

We propose an aerodynamic force decomposition which, for the first time, allows a thrust/drag bookkeeping in two-dimensional viscous and unsteady flows. Lamb-vector-based far-field methods are used at the scope, and the paper starts with extending recent steady compressible formulas to the unsteady regime.
