Study the Effect of Adding Alpha Aluminium Oxide to The Working Fluid in The Heat Pipe

In this research paper, we practically study the effect of adding a nano-material of alpha-type aluminium oxide on the performance of the heat pipe in addition to the working fluid in the heat pipe with a volumetric mixing ratio of 5%. Through the experiment, we find that the surface temperature of the pipe increases with the increase in the heat flux applied to the heat pipe and is higher In the case of adding aluminium oxide to water, and we notice the pressure inside the tube decreases when the working fluid is a mixture of water with aluminium oxide compared to water, the deposition of alpha aluminium oxide on the screen mesh wick and deposition on the wall of the tube in the inner surface leads to a reduction in heat transfer from the evaporator to the condenser As a result, all of the above leads to an increase in thermal resistance, Efficiency decreases by between (2-40)% in case of adding a1203 type alpha.
