The characteristics of a pulsatile flow through stenosis are already well known, however, mass transport around stenosis is not yet well understood. In this study, mass transport in the pulsatile flow between flat plates with asymmetric stenosis is analyzed numerically. The effects of the pulsation and asymmetry of the stenosis on the mass transport are investigated. Flow pattern, concentration pattern and the distribution of the wall concentration are obtained. It is found that an asymmetry of the stenosis increases the wall concentration downstream of the stenosis. In the asymmetric stenosis case, the wall concentration downstream of the stenosis recovers at a lower pulsatile frequency than the symmetric stenosis case.
