Background Abdominal aortic aneurysms (AAA) are a major cause of morbidity and mortality in the US. The most common location of AAA is the infrarenal abdominal aorta where oscillatory flow is present over the cardiac cycle, figure 1. Oscillatory flow is known to initiate an inflammatory response in endothelial cells. Patients with lower extremity traumatic amputations have a 5-fold increase in ...

In the present investigation, a mathematical model is developed to study the flow of blood in a multiple stenosed artery employing velocity slip condition under the externally applied transverse magnetic field. Blood is modeled as Herschel-Bulkley fluid to represent the non-Newtonian character of blood in small blood vessels. The expressions for wall shear stress, volumetric flow rate, axial ve...

an attempt is made for the first time to solve the quadratic and cubic model of magneto hydrodynamic poiseuille flow of phan-thein-tanner (ptt). series solution of magneto hydrodynamic (mhd) flow is developed by using homotopy perturbation method (hpm). results are presented graphically and the effects of non-dimensional parameters on the flow field are analyzed. the results obtained reveals ma...

Analytical investigation of MHD blood flow in a porous inclined stenotic artery under the influence of the inclined magnetic field has been done. Blood is considered as an electrically conducting Newtonian fluid. The physics of the problem is described by the usual MHD equations along with appropriate boundary conditions. The flow governing equations are finally transformed to nonhomogeneous se...

We investigate oscillatory blood flow in an elastic artery and in the presence of stenosis, whose form is given analytically. The stenosis is a condition where an artery wall thickens as a result of fatty materials such as cholesterol. We consider the case of very low pulse frequency that can be the case for patients whose hearts beat too slowly, but with arbitrary value of the ratio γ of the a...

Abstract The analytical study of MHD oscillatory, unsteady, natural convective viscous incompressible dissipative flow through vertical channel filled with porous medium in the presence heat source effect and thermal radiation have been discussed. time-dependent equations scheme such as equation fluid motion transfer are derived solved by a suitable method. MATLAB software is used to plot figur...
