چکیده
Abstract The present paper analyzes an unsteady magnetohydrodynamic blood flow model of visco-elastic fluid through inclined porous stenosed artery with body acceleration and slip effect. Navier-Stokes equations have been used to describe the model. governing equation is solved by analytic method considering as incompressible, fluid, suspension RBC’s in plasma. Axial velocity, acceleration, rate, shear stress are derived numerically using finite Laplace Hankel transformation their inverse. effect parameters such visco-elasticity parameter, Womersley number, Hartmann inclination angle, parameter slip, frequency analyzed. velocity reduces number enhance it enhances enhancement angle. study beneficial for finding porosity factor when a human exposed MRI CT scan.

متن کاملPulsatile MHD Flow in an Inclined Catheterized Stenosed Artery with Slip on the Wall
Catheter is commonly used by the surgeons for various reasons in the treatment of a patient suffering with cardiovascular diseases. Catheterization increases the mean flow resistance in the arterial blood flow and many other complications are associated with the presence of catheter in the artery. Effects of catheter in stenosed artery can be estimated non-invasively by means of hemodynamic ind...
متن کاملAn implicit finite difference scheme for analyzing the effect of body acceleration on pulsatile blood flow through a stenosed artery
With an aim to investigate the effect of externally imposed body acceleration on two dimensional,pulsatile blood flow through a stenosed artery is under consideration in this article. The blood flow has been assumed to be non-linear, incompressible and fully developed. The artery is assumed to be an elastic cylindrical tube and the geometry of the stenosis considered as time dependent, and a co...
