A Result Paper on Thermal Performance of Heat Pipe By Using Nanofluid
The effect of nanofluid on the heat transfer has investigated. The thermal performance of heat pipe for nanofluid was tested experimentally. The experimental set up which contains heat pipe, heater, control panel, temperature indicator, motor, measuring flask etc. has been prepared. The water based Al2O3 nanofluid has used. The five different concentrations 0.1%, 0.3%, 0.5%, 0.7% and 0.9% of water based Al2O3 nanofluid have used in the heat pipe for five different heat inputs 50W, 100W, 150W, 200W and 250W. The heat transfer in the heat pipe for different concentrations of water based Al2O3 nanofluid for different heat input has been calculated. The heat transfer rate has increased in the heat pipe when Al2O3 nanofluid was used and it has lowered when pure water was used. For 0.3%, 0.5% and 0.7% concentration of Al2O3, heat transfer has increased and for 0.9% concentration it has lowered to some extent in heat pipe. The nanofluid helps to increase heat transfer rate and thermal performance of heat pipe.
