摘要:
In this letter, the non-Newtonian behavior of the blood flow is captured by using Cross fluid model within curved multiple stenosed channel. The generations of entropy within blood flow due to dissipation and magneto-hydrodynamics effects are also explored in this study. The 2 dimensional curvilinear co-ordinate system is incorporated mathematically in the fundamental proposed physical system. After then, the obtained system of equations is reduced to normalized form with the insertion of mild stenotic condition as well. Explicit finite difference technique is induced on these physical equations to acquire the numerical solution. Flow characteristics such as wall shear stress and velocity are calculated at the stenotic throat of the curved vessel in order to originate the Bejan number (Be) and Entropy generation parameter (NG) numerically. In the last section, the profiles of velocity, Bejan number, temperature and entropy generations are portrayed with the variation of different emerging parameters such as curvature Rc, Wessenburg (We) number, magnetic parameter and Brickmann number(Br). From the obtained results, it is concluded that the values of Bejan number (Be) and Entropy generation parameter (NG) are highly affected with the variation of magnetic and curvature parameters. Impacts of different parameters (such as Brickmann number (Br) and curvature effects (Rc)) on blood flow pattern are visualized in streamlines plot for general reader.
