Numerical Investigation of Thermal Radiation and Viscous Effects on Entropy Generation in Forced Convection Blood Flow over an Axisymmetric Stretching Sheet

Abstract

Numerical and analytical investigation of the effects of thermal radiation and viscous heating on a convective flow of a non-Newtonian, incompressible fluid in an axisymmetric stretching sheet with constant temperature wall is performed. The power law model of the blood is used for the non-Newtonian model of the fluid and the Rosseland model for the thermal radiative heat transfer in an absorbing medium and viscous heating are considered as the heat sources. The non-dimensional governing equations are transformed to similarity form and solved numerically. A parameter study on entropy generation in medium is presented based on the Second Law of Thermodynamics by considering various parameters such as the thermal radiation parameter, the Brinkman number, Prandtl number, Eckert number.

Entropy Analysis for Cilia-Generated Motion of Cu-Blood Flow of Nanofluid in an Annulus

“…Initially, Bejan [35] proposed the theory of entropy generation in heat transfer and fluid flow systems. Some relevant studies on the subject can be seen in the list of references: Pakdemirli and Yilbas [36], Aiboud and Saouli [37], Sheikholeslami et al [38], Galanis and Rashidi [39], Rashidi et al [40], Ellahi et al [41], Bhatti et al [42] and Jamalabadi et al [43] and Upreti et al [44].…”

Numerical Investigation of Oxygenated and Deoxygenated Blood Flow through a Tapered Stenosed Arteries in Magnetic Field

“…This interruption includes the movement of conductive physiological fluids. The transient condition could be aroused from periodic body acceleration [25] or stretching walls [26] that affect the shear‐thinning Non-Newtonian response [27–36]. Various fluid model [37–45] such as Carreau fluid model [37,38], Micropolar [39], power-law fluid [40], homogeneous Newtonian fluid [41–44], two-layered [45], Casson Fluid [46], Bingham plastic fluid [47], CNT nanofluid suspension [48,49], were used for the blood flow through artery in the presence of stenosis and strong static magnets [50] or spatially varying magnetic field [51–55].…”
