The effects of water-CuO nanofluid flow on heat transfer inside a heated 2D channel

Effects of Rib Shapes on Heat Transfer Characteristics of Turbulent Flow of Al2O3-Water Nanofluid inside Ribbed Tubes

In this paper, convection heat transfer of Al2O3-water nanofluid turbulent flow through internally ribbed tubes with different rib shapes (rectangular, trapezoidal and semi-circular) is numerically investigated. For each rib shape, the optimum geometric ratio and volume fraction were calculated using entropy generation minimization technique. The governing equations in...

Experimental Investigation on CuO/Water Nanofluid Effect on the Heat Transfer Rate of Heat Pipe Network

In this study, a new configuration of heat pipes as Heat Pipe Network is introduced. Here, the heat pipe network is designed, constructed and then has been under the performance assessment. This heat pipe network consists of 4 vertical heat pipes connected to evaporator collector from bottom and condenser collector from top. In order to investigate the effect of nanofluids on the thermal effici...

Investigations on heat and momentum transfer in CuO-water nanofluid

This paper presents results of investigations on the application of CuO-water nanofluids for intensification of convective heat transfer. Performance of nanofluids with 2.2 and 4.0 vol.% CuO NPs (nanoparticles) content were examined with regard to heat transfer coefficient and pressure losses in case of turbulent flow in a tube. Negligible impact of examined nanofluid on heat transfer improveme...

Flow field and heat transfer of MgO-Ag/water micropolar hybrid nanofluid in a permeable channel

In this study, the least square method is applied to study the laminar flow, heat transfer and microrotation of MgO-Ag/water micropolar hybrid nanofluid in a permeable channel. The bottom wall is hot and coolant fluid is injected into the channel from the top wall. The base fluid in the channel is water and volume fraction of nanoparticle (50% Ag and 50% MgO by volume) is between 0 and 0.02. By...
