Abstract
The identification of vortex, sound and heat motions and the interactions among them are discussed by means of velocity vector split and perturbation method in this paper. Especially the shear flow is considered. All the obtained weakly non-linear equations have clear physics concept. Basing on the analysis, the interaction between first order sound and vortex and the creation of the second order vortex are studied and some experiment phenomena of airfoil flow control by sound are explained.
