Abstract

In this project, the optimum concentration of a nanofluid needed in a heat pipe to maximize heat transfer is being conducted. A heat pipe is made up of three parts: the shell, wick, and the working fluid. The heat pipe is also divided into three sections along its length, which are the evaporator, adiabatic, and condenser. Nanofluids are used to improve thermal performance of a heat pipe by reducing thermal resistance and the temperature gradient along the pipe while also increasing the overall heat transfer coefficient. This is done by dispersing highly conductive solid nanoparticles, Aluminum Oxide, into the working fluid, water. An increase in thermal performance is to be expected when the optimum concentration of nanofluid is found in comparison to when the working fluid in a heat pipe is water. We have measured the temperature profile of the heat pipe under various heat loads with water as the working fluid. Our initial results show 10% error in average when compared to the analytical data. It was at the higher heat input values where the experimental and analytical results became closer.

Summary of research results to be presented

We have measured the temperature profile of the heat pipe under various heat loads with water as the working fluid. Our initial results show 10% error in average when compared to the analytical data. It was at the higher heat input values where the experimental and analytical results became closer.
