The existing analysis deals with heat transfer occurrence on peristaltic transport of a Carreau fluid in a rectangular duct. Flow is scrutinized in a wave frame of reference moving with velocity away from a fixed frame. A peristaltic wave propagating on the horizontal side walls of a rectangular duct is discussed under lubrication approximation. In order to carry out the analytical solution of velocity, temperature, and pressure gradient, the homotopy perturbation method is employed. Graphical results are displayed to see the impact of various emerging parameters of the Carreau fluid and power law index. Trapping effects of peristaltic transport is also discussed and observed that number of trapping bolus decreases with an increase in aspect ratio .

矩形管中卡罗流体的蠕变流动的热效应和不同波形分析

现有分析涉及在矩形管道中蠕动输送Carreau流体时发生的传热问题。在参考波框架中仔细检查流量，该参考框架以远离固定框架的速度移动。在润滑近似下，讨论了在矩形管道的水平侧壁上传播的蠕动波。为了进行速度，温度和压力梯度的解析解，采用了同伦摄动法。显示图形结果以查看Carreau流体和幂律指数的各种新兴参数的影响。还讨论了蠕动运输的诱捕效果，并观察到诱捕药丸的数量随长宽比的增加而减少。
