• In this paper numerical analysis has been performed on mass transport from daughter channel wall to pulsatile flow through a two-dimensional orthogonal branch. The transport of a substance such as cholesterol from artery to blood flow is modeled, and is examined by numerically calculating the nonlinear mass transport equations for convective and diffusive processes. Particular attention is paid to the variation of mass transport at the separated region on the daughter wall of branch. The steady flow is calculated so that the effects of pulsation can be assessed. Consequently, the following results are obtained: 1. The mass transport is strongly dependent on flow region and pulsation. 2. Reduction of the mass transport occurs at the separated region on the daughter wall of branch. 3. In a simple pulsatile flow, the mass transport at this separated region on the daughter wall steeply changes at the time when the flow rate increases from zero flux.
