A note on the Galilean invariance of aerodynamic force theories in unsteady incompressible flows

A note on the Galilean invariance of aerodynamic force theories in unsteady incompressible flows As a basic principle in classical mechanics, the Galilean invariance states that the force is the same in all inertial frames of reference. But this principle has not been properly addressed by most unsteady aerodynamic force theories, if the partial force contributed by a local flow structure is to be evaluated. In this note, we discuss the Galilean-invariance conditions of the partial force for several typical theories and numerically test what would happen if these conditions do not hold. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Mechanica Sinica Springer Journals

Abstract

As a basic principle in classical mechanics, the Galilean invariance states that the force is the same in all inertial frames of reference. But this principle has not been properly addressed by most unsteady aerodynamic force theories, if the partial force contributed by a local flow structure is to be evaluated. In this note, we discuss the Galilean-invariance conditions of the partial force for several typical theories and numerically test what would happen if these conditions do not hold.
