Induced dusty flow due to normal oscillation of wavy wall (Q5945300)

Summary: A two-dimensional viscous dusty flow induced by normal oscillation of a wavy wall at moderately large Reynolds number is studied on the basis of boundary layer theory in the case where the thickness of boundary layer is larger than the amplitude of wavy wall. Solutions are obtained as series expansions with respect to small amplitude by a regular perturbation method. Graphs of velocity components, both for outer flow and inner flow, are given for various values of mass concentration of dust particles. The inner and outer solutions are matched. An application is given to fluid and dust transportation without external pressure.
