Characteristics of Newtonian heating on electrically conducting water-based nano-fluid with in permeable vertical micro-channels

Abstract

Micro-channels are extensively used in the electrical and medical industries to advance the heat transfer of cooling devices. For the present study, the heat transfer from a porous vertical micro-channel heat sink here in this work, nanofluid, was considered a working fluid inside the micro-channel.  The four most commonly used nanofluid is considered during the work, that is and. The mixture of nano-sized copper and alumina particles is considered to be cool the micro-channel heat sink. The said physical model is translated into mathematical expressions are solved the governing equations analytically. It was observed that all the nano-fluids thermophysical properties vary with the addition of nano-particles, and thermal conductivity is increasing. The consequences of solid nano-particle, porosity and heat source slip parameter, Darcy number, Hartmann number, and slip length are computed.
