چکیده
|
The paper numerically presents laminar forced convection of a nanofluid flowing in a duct at microscale. results were compared with both analytical and experimental data and observed good concordance with previous studies available in the literature. influences of brinkman and reynolds number on thermal and hydrodynamic indexes have been investigated. for a given nanofluid, no change in efficiency (heat dissipation to pumping power) was observed with an increasing in reynolds number. it was shown that the pressure was decrease with an increase in brinkman number. dependency of nu increment changes with substrate material.
