Weakly non-linear analysis on identification of vortex sound & heat and their interactions in shear flow

Abstract

The identification qf vortex, sound and heat motions cmd the interactions among them are discussed by means of velociO" rector split and perturbatton method in this paper. Especialh the shear ,floB is considered. All the obtained weakh" non-linear equations hare clear physics concept. Basing on the anah'sis, the interaction betueen first order sound and rortex and the creatton of the second order rortex are studied and some experiment phenomena of aicfoil.flow control by sound are explclined.
