The velocity distribution and heat transfer improvement in a two-dimensional channel filled with water-CuO nanofluid is numerically studied. flow assumed laminar one-phase Newtonian behaviour. Pure water considered as the base fluid, four different volume fractions of CuO nanoparticles are examined. A constant source–sink to cover entire length bottom wall while upper thermally insulated. contr...

In this numerical study, 4 types of hybrid nanofluid, including Ag-MgO/water, TiO2-Cu/water, Al2O3-CuO/water, and Fe3O4-multi-wall carbon nanotube/water, have been considered potential working fluid in a single U-tube borehole heat exchanger. The selected nanofluid is then analyzed by changing the volume fraction Reynolds number. Based on results, Ag-MgO/water chosen as most favorable carrier f...

A coupled molecular dynamics (MD)-stochastic model has been developed for predicting the thermal conductivity of a hypothetical water based Zn-nanofluid taking into account the heat transfer during and after collision of the nanoparticles with the heat source. The model has predicted a somewhat lower enhancement in thermal conductivity of water based Zn-nanofluid compared to water based Cu-nano...
