THE EFFECT of the USE of DIFFERENT NANOFLUIDS on the HEAT TRANSFER PERFORMANCE of a HEAT EXCHANGER

, 2022
The most important problem of heating and cooling systems is the removal of heat from the system. Heat exchangers are the most critical equipment of such systems. However, the use of nanofluids has increased significantly in recent years due to the design limitation of heat exchangers. In this study, the effect of using different nanofluids on the heat

Heat Transfer Performance of Axially Grooved Heat Pipes

Heat Transfer Performance of Axially Grooved Heat Pipes
This paper describes experiments and analysis of the heat transport capability of axially grooved heat pipes. The heat pipes were made of aluminum axially grooved extruded pipes and the working fluid was R11. The effects of fluid inventory and inclination angle on the capillary pumping limit were investigated.
