Heat, mass transfer, and non-Newtonian fluid flow processes have gained significant interest in various industrial applications due to their substantial significance in the fields of technology, engineering, and science. The aforementioned processes hold significance in the context of polymer solutions, porous industrial materials, ceramic processing, oil recovery, and fluid beds. This study aims to investigate the impact of temperature-dependent viscosity and thermal conductivity on the cilia-driven flow of tangent hyperbolic fluid with mass and heat transfer. The objectives include analyzing how these variable properties affect the velocity, temperature, and concentration profiles within the fluid flow, thereby providing insights into potential applications in bioenergy systems and enhancing the understanding of non-Newtonian fluid dynamics. Viscous dissipation has been taken into consideration. Firstly, governing nonlinear coupled equations are solved in a fixed frame, and then the results are tracked in the wave frame. MATHEMATICA's NDSolve command is utilized to graphically discuss the findings for several different flow parameters. Analytically stated, solving a problem with such a coupled and nonlinear system is tough. The effect of new parameters is discussed on velocity and temperature profile and graphically shown. It has been observed that the thermal conductivity is improved at moderately low temperatures, whereas the opposite pattern is seen at comparatively high temperatures. On the other hand, the temperature distribution demonstrates a behaviour consistent with lowering as the number of heat Bolus increases. The findings that were provided offer beneficial insight into bioenergy systems and serve as a helpful benchmark for both experimental and extra-progressive computational Multiphysics models.

可变流体特性对传热传质通道中纤毛驱动的切线双曲线流体流动影响的数值研究:微流体泵的新方法



热、传质和非牛顿流体流动过程由于其在技术、工程和科学领域的重大意义而在各种工业应用中引起了极大的兴趣。上述过程在聚合物溶液、多孔工业材料、陶瓷加工、石油回收和流化床领域具有重要意义。本研究旨在研究温度依赖性粘度和导热率对具有传质和传热的切线双曲流体的纤毛驱动流动的影响。目标包括分析这些可变特性如何影响流体流动中的速度、温度和浓度分布,从而深入了解生物能源系统中的潜在应用,并增强对非牛顿流体动力学的理解。已考虑粘性耗散。首先,在固定坐标系中求解控制非线性耦合方程,然后在波动坐标系中跟踪结果。 MATHEMATICA 的 NDSolve 命令用于以图形方式讨论几个不同流动参数的结果。从分析上来说,解决这样一个耦合和非线性系统的问题是很困难的。讨论了新参数对速度和温度分布的影响并以图形方式显示。据观察,导热率在适度低温下得到改善,而在相对较高的温度下则出现相反的情况。另一方面,温度分布表现出随着热推注数量增加而降低的行为。 所提供的研究结果提供了对生物能源系统的有益见解,并为实验和超渐进计算多物理模型提供了有用的基准。
