Abstract

The melting phenomenon plays a critical role in optimizing the performance of power storage, electronic cooling, and semiconductor devices. The present study aims to analyze the melting effect on the flow of Carreau fluid over a stretchable cylinder, with special consideration given to the impact of quadratic thermal radiation. Similarity variables and the homotopy analysis method are used to simplify and determine the semi-analytical homotopic solutions of the governing equations. The present findings reveal that the melting parameter increases the heat transfer rate by more than 10% for both fluids, water (Pr = 0.71), and polymer (Pr = 10). However, as the temperature ratio due to quadratic radiation increases, the local Nusselt number for water has been reduced by 25%, and an even more substantial reduction is observed for the polymer. The present study offers valuable insights into achieving optimal efficiency in electronic devices.

带二次辐射的可拉伸圆柱体周围卡诺流体流动的熔化效应热分析

熔化现象在优化功率存储、电子冷却和半导体器件的性能方面起着至关重要的作用。本研究旨在分析卡诺流体在可拉伸圆柱体上流动时的熔化效应，并特别考虑了二次热辐射的影响。研究采用相似变量和同调分析方法来简化和确定支配方程的半解析同调解。目前的研究结果表明，对于水（= 0.71）和聚合物（10）这两种流体，熔化参数会使传热速率增加 10%以上。然而，随着二次辐射温度比的增加，水的局部努塞尔特数降低了 25%，聚合物的降低幅度更大。本研究为实现电子设备的最佳效率提供了宝贵的见解。
