Thermal Performance Investigation of Heat Transfer Characteristics of a Two Phase Thermosyphon using Hybrid Nanofluid

Abstract

It is very important to increase the rate of Heat transfer in many areas especially in heat exchangers, gas turbine, air coolers, different power plant, where transfer of heat Energy is an important factor. A tremendous amount of effort had taken to develop new methods to increase heat transfer. It demonstrated that nanofluid can have remarkable higher rate of heat transfer than those of the base fluid. In this paper a thermal performance of a circular heat pipe with hybrid nanofluid (i.e. copper oxide and carbon nanotube) is carried out at different heat input, at different angle of inclination and at different concentration of nanoparticle on two phase closed thermosyphon. Result of this experiment shows that efficiency of HP increases with use of nanofluid. Maximum efficiency observed at inclination angle 75° and it is 33.24%.
