Design and Development of a High-Performance Heat Pipe with Nano Fluids

Abstract

Heat dissipation in the space application is very much necessary as it contains some critical components. The satellite work under very extreme high and low temperatures depending on the satellite position in the orbit. Also, the electronics component on panels generates heat. To maintain the temperature of the components, the grooved heat pipe (GHP) is one of the best solutions. In the GHP for space applications, the capillary action phenomenon plays a major role to transfer the liquid from the condenser side to the evaporator side as gravity is zero.
This paper focuses on the numerical simulation of heat and mass transferrin the GHP for space application. The CFD simulation is done using Ansys Fluent software. The Ω shaped axial micro-channeled GHP made from aluminum is considered for this study. The volume of fluid (VOF) multiphase model along with the Lee model is used to perform the mass transfer phenomenon. The working fluid in the heat pipe is Ammonia. The GHP under consideration is simulated to study the effects for different heat load and filling ratio conditions.
The simulated design will be fabricated using metal 3D printers and then the performance will be studied such as the temperature differences, the thermal resistance as well as the steady state time. Finally, nano particles will be used the same parameters will studied and compared.
