NUMERICAL INVESTIGATION OF THE STABILITY OF FLOWS INDUCED BY A SURFACE ACOUSTIC WAVE ALONG A SLAB
This paper investigates the stability of flows induced by a surface acoustic wave (SAW) propagating along the deformable walls in a confined parallelplane mi-crochannel in the laminar flow regime. The governing equation which was derived by considering the nonlinear coupling between the waving interface and viscous fluids is linearized and then the problem is solved by a verified code based on the spectral method together with the associated interface and slip velocity boundary conditions. The value of the critical Reynolds number for the Knudsen number (Kn) being 0.001 was found to be near 1441 which is much smaller than the rigid-wall case : 5772 for conventional pressure-driven flows.
