The current work intends to look into the effects of variable liquid properties on the magnetohydrodynamics of peristaltic flow exhibited by Jeffrey fluid through a compliant-walled channel. In order to make realistic approximations for the flow characteristics of blood, the channel is considered to be inclined and porous. Furthermore, convective boundary conditions and concentration slip have been employed in the analysis. The mathematical formulation is established on the grounds of low Reynolds number and long wavelength approximations. Perturbation solution is obtained for the resulting non-linear differential equations of momentum and energy for small values of variable viscosity and variable thermal conductivity, whereas exact solution is found for the concentration field. The impact of various parameters included in the study is displayed graphically. A rise in the parameter for variable viscosity is found to accelerate the fluid flow, hence resulting in an increased bolus size. For variable thermal conductivity, a similar influence on the heat transfer was observed. The behaviour of the skin-friction coefficient, Nusselt and Sherwood numbers have also been plotted for the pertinent parameters.

传热传质对杰弗里流体MHD蠕变机理的可变液体性质的血流动力学

当前的工作旨在研究可变液体性质对杰弗里流体通过顺应壁通道所表现出的蠕动流的磁流体动力学的影响。为了对血液的流动特性做出逼真的近似,该通道被认为是倾斜且多孔的。此外,在分析中还采用了对流边界条件和浓度滑动。数学公式是基于低雷诺数和长波长近似值建立的。对于可变粘度和可变热导率的较小值,可以使用所得动量和能量非线性微分方程的摄动解,而对于浓度场则可以找到精确的解。研究中包含的各种参数的影响以图形方式显示。发现用于可变粘度的参数的增加加速了流体流动,因此导致了大丸团尺寸的增加。对于可变的热导率,观察到对热传递的类似影响。还针对相关参数绘制了皮肤摩擦系数,Nusselt和Sherwood数的行为。
