| Summary: | This project is a study about the effect of body acceleration on blood flow in tapered overlapping stenosed artery. The blood is treated as Newtonian fluid and it is assumed to be unsteady, laminar, two dimensional and axisymmetric. Thus, the governing Navier-Stokes equation (continuity equation and momentum equation) are solved where the equation is in the term of cylindrical coordinates and transformed them using radial coordinate transformation. Then, the governing equation with the boundary conditions is discretized by using finite difference method. So, for the numerical results to be obtained, MATLAB programming are developed and are presented graphically. In conclusion, the blood flow characteristics which are the axial and radial velocities of blood can easily determine under the effect of body acceleration. With the presence of body acceleration, the velocity profiles win decrease. The tapered artery with body acceleration is higher than the absence of body acceleration. |
