Analysis of thermal behavior of a porous fin fully wetted with nanofluids: convection and radiation

摘要

The analysis of heat movement through longitudinal permeable fin fully wetted by nanoliquid has been modeled in the presence of natural convection and radiation condition. Three kinds of water based nanoliquids having titanium dioxide, aluminium oxide and copper nanoparticles are used for the study. The derived energy equation has been resolved numerically by Runge Kutta Fehlberg method. The influence of geometric and flow factors on the temperature distribution of the fin are discussed in detail by means of plotted graphs. It is found that, Cu-water nanoliquid enhances more heat transport from the fin surface. (C) 2020 Published by Elsevier B.V.
