摘要

This paper continues the work of Zhu et al [8]. The closed-form expressions for thernevaluation of forces on a body in compressible, viscous and rotational flow derived in thernprevious paper have been extended to different forms. The expressions require only arnknowledge of the velocity field (and its derivatives) in a finite and arbitrarily chosenrnregion enclosing the body. The equations are implemented on three-dimensional inviscidrnflows over wings and wing/body combinations. Further implementation on threedimensionalrnviscous flows over wings has also been investigated.
