Study on Heat Pipe : 2nd Report, Heat Transfer Mechanism in the Evaporator Zone of Heat Pipe

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...

Heat Transfer of Nanofluid in a Double Pipe Heat Exchanger

This paper investigates the enhancement of heat transfer coefficient and Nusselt number of a nanofluid containing nanoparticles (γ-AL2O3) with a particle size of 20 nm and volume fraction of 0.1%-0.3% (V/V). Effects of temperature and concentration of nanoparticles on Nusselt number changes and heat transfer coefficient in a double pipe heat exchanger with counter turbulent flow are investigate...

An experimental investigation of heat transfer of Fe2O3/Water nanofluid in a double pipe heat exchanger

One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...
