Abstract

Pulsatile flow and mass transport between flat plates with asymmetric stenosis is analyzed numerically. The fluid is assumed to be Newtonian and incompressible, and the flow is assumed to be periodic in time. The effect of asymmetric stenosis on mass transport is investigated. Flow pattern, concentration pattern and distribution of wall concentration are obtained. It is found that the asymmetry of stenosis increases concentration on the wall downstream of stenosis. In high Schmidt number flow, concentration on the wall of asymmetric stenosis recovers in smaller Stokes number compared with that of symmetric stenosis.
