In this work peristaltic transport of Sutterby liquid with temperature dependent thermal conductivity in curved configurations is addressed. Inclined magnetic field is considered. Energy expression is modeled with effects of viscous dissipation, non-linear thermal radiation, variable thermal conductivity, Joule heating and heat source/ sink. Lubrication approach in formulation has been implemented. Irregularities are discussed by entropy in the process of heat transfer. Perturbation method has been used for velocity and stream function in this study. However, energy equation is solved numerically. Quantities of interest via important parameters are graphically analyzed. These results witness that velocity decreases both for magnetic field and fluid parameters. Temperature decays for variable thermal conductivity parameter and radiation; whereas, it increases for heat absorption parameter Q(>0). Irregularity is minimum via entropy for enhanced thermal conductivity and radiation parameters. Heat transfer rate increases for increased values of Brinkmann number.

受温度依赖性导热系数和非线性热辐射影响的Sutterby材料磁蠕动的熵最小化
在这项工作中,解决了萨特比液体在弯曲配置中蠕动运输的问题,该运输具有与温度相关的导热系数。考虑倾斜磁场。用粘性耗散,非线性热辐射,可变热导率,焦耳热和热源/吸收器的影响对能量表达进行建模。配方中的润滑方法已经实施。在传热过程中,通过熵来讨论不规则性。在这项研究中,摄动法已被用于速度和流函数。但是,能量方程是数值求解的。通过重要参数对感兴趣的数量进行图形分析。这些结果证明,磁场和流体参数的速度均降低。温度因可变的热导率参数和辐射而衰减;然而,Q(> 0)。通过熵可以最大程度地减少不规则性,从而提高热导率和辐射参数。随着布林克曼数的增加,传热速率增加。
