Abstract
In the present study, conjugative heat transfer of nano fluid in a horizontal rectangular duct using CuO-Water is numerically investigated. The fluid flow is assumed to be single phase, laminar, incompressible, steady and three dimensional in nature. A constant wall heat flux has been allowed through the wall and corresponding overall heat transfer coefficient and temperature field along with the Nusselt number variation have been obtained. The detail velocity field, temperature field, friction factors have been derived, validated and presented for different Reynolds number and particle volume fraction of the nano particle. The most significant achievement is the enhancement of the overall heat transfer coefficient and Nusselt number indicating those parameter increases with the increase in the nano particle percentage. The Reynolds number has an important bearing on the result since an increase in Re also indicates the improvement of heat transfer parameters.
