Irreversibility analysis of nanofluid flow in a vertical microchannel with the influence of particle shape

Augmentation of thermal performance in heat transfer system has become research hotspot nowadays. Numerous techniques are carried out to pick up the effective heat transport mechanism for designing high efficient thermal frameworks which has extensive practical uses in industrial process. In the current study, mixture model has been implemented for better describing the characteristics of nanoparticles in a vertical microchannel. The nondimensional equations are computed by using Runge Kutta Fehlberg method. Effect of heat source, buoyancy force and convective boundary on the thermal system has been demonstrated. The role of spheroidal nanoparticles on thermal conductivity of the conventional fluid has been examined. The causes of irreversibilities in a microchannel due to nanoliquid flow has been reported in the current research work. It is obtained that Aluminum foam has higher thermal field compared toAl(2)O(3). Entropy generation is reduced by lowering Eckert number and Grashof number. It is explored that nanofluid containing oblate shaped nanoparticels has higher thermal conductivity ratio.

Automated summary

The study used a mixture model to describe the characteristics of nanoparticles in a vertical microchannel and found that spherical nanoparticles have an impact on the thermal conductivity of conventional fluids. It also explored the irreversibilities in microchannels caused by nanoliquid flow and how to reduce entropy generation.
