Abstract

The analysis of nanofluids under various physical scenarios convinced the researchers and scientists because of their broad range of applications in potential area of the current time like chemical engineering, biomedical engineering and applied thermal engineering etc. To give the final shape of many industrial and engineering processes, enhanced heat transfer desired, therefore, the study of AlO-HO, γAlO-HO, AlO-CHO, and γAlO- CHO nanofluids is reported. The model successfully achieved after mathematical operations and by appealing similarity transforms. To examine the behavior of heat transfer, numerical tools utilized and performed the results. It is observed that enhanced heat transfer in AlO-HO, γAlO-HO, AlO-CHO, and γAlO-CHO could be attained by setting nanoparticles concentration up to 20%. For AlO-HO, γAlO-HO, optimum heat transfer trends noticed due to their prominent thermophysical values. Also, fewer effects of combined convection on examined.

摘要

由于纳米流体在各种物理场景下的分析在当前时间的潜在应用领域，如化学工程、生物医学工程和应用热工程等方面具有广泛的应用，因此引起了研究人员和科学家的关注。为了给许多工业和工程过程赋予最终的形状，需要增强传热，因此，研究了 AlO-HO、γAlO-HO、AlO-CHO 和 γAlO-CHO 纳米流体。通过数学运算和相似变换的调用，成功地实现了模型。为了研究传热行为，利用数值工具并进行了结果分析。结果表明，通过将纳米粒子浓度设置在 20%以下，可以在 AlO-HO、γAlO-HO、AlO-CHO 和 γAlO-CHO 中获得增强的传热效果。对于 AlO-HO、γAlO-HO，由于其突出的热物理值，观察到了最佳的传热趋势。此外，还研究了对复合对流的较小影响。
