Abstract

In pursuit of improved thermal transportation, the slip flow of Casson nanofluid is considered in the existence of an inclined magnetic field and radiative heat flux flow over a non-linear stretching sheet. The viscosity of the fluid is considered as a function of temperature along with the convective thermal boundary condition. Numerical solutions are obtained via Runge-Kutta along with the shooting technique method for the chosen boundary values problem. To see the physical insights of the problem, some graphs are plotted for various flow and embedded parameters on temperature function, micro-organism distribution, velocity, and volume fraction of nanoparticles. A decline is observed in the velocity and the temperature for Casson fluid. Thermophoresis and Brownian motion incremented the temperature profile. It is also found that thermal transportation can be enhanced in the presence of nanoparticles and the bioconvection of microorganisms. Present results are useful in the various sectors of engineering and for heat exchangers working in various technological processors. The main findings of the problem are validated and compared with those in the existing literature as a limiting case.

倾斜磁场和变粘度对卡森纳米流体在非线性拉伸薄片上滑动流动的生物对流影响

为了改善热输运，考虑了卡森纳米流体在倾斜磁场和辐射热流流过非线性拉伸片的情况下的滑移流动。流体的黏度是温度与对流热边界条件的函数。采用龙格-库塔法结合射击技术对所选边值问题进行了数值求解。为了了解这个问题的物理意义，我们绘制了一些关于温度函数、微生物分布、速度和纳米颗粒体积分数的各种流动和嵌入参数的图表。卡森流体的流速和温度均有下降。热泳动和布朗运动增加了温度分布。研究还发现，纳米颗粒的存在和微生物的生物对流可以增强热传递。目前的结果对工程的各个部门和在各种工艺处理器中工作的热交换器是有用的。作为一个极限情况，验证了问题的主要发现，并与现有文献中的发现进行了比较。
