Flow of blood structure is presented in terms of stream line projections at different percentages of deposition against various Reynolds numbers. The impact of atherosclerosis is investigated on the vortex enhancement and intensity. The predicted results are computed in terms of stream function for quantifying the reattachment length and re-circulating flow rate of blood at various Reynolds numbers and different percentages of blockage. The results show that flow of blood is disturbs at the vicinity of blockage, especially in the down stream area that leads to the formation of vortexes. It is observed that the length of vortex increases along with the deposition levels as well as with increasing inertia .To solve the Navier-Stokes equations, together with the incompressibility constraints a semi-implicit time stepping procedure, namely Taylor- Galerkin/Pressure-correction finite element scheme has been employed.
