People use heatpipes in a variety of ways to move heat from one end to the other. It is possible to have different types of "wick" inside a heat pipe. Grooved wick heatpipes can move heat against gravity by evaporating and then condensing. In the present investigation, experimental analysis on grooved wick heatpipe is performed. In the experiment performance analysis is conducted for various heat inputs and cooling flow rates at condenser zone for grooved wick heatpipe. From the experimental data, calculated the thermal resistance and heat transfer co-efficient by standard formulae of the heatpipe. It was found that with increase in heat input, the heat transfer co-efficient also increases, but thermal resistance decreases. Also concluded that with increase in flow rate at the condenser end, the efficiency of the heat pipe also increases. For the numerical analysis, grooved wick heatpipe is modeled by using Solidworks (2020) of the available standard size. ANSYS FLUENT was used to investigate the thermal performance of heatpipe and analyze the multi-phase process. The design parameters and boundary conditions are taken from the experimentation and performed CFD analysis. The temperature distributions, volume fractions of vapour and velocity variations are found. A comparison is being made between the experimentation and CFD simulation and found that there is a deviation of 10 to 12 % between these results. [ABSTRACT FROM AUTHOR] |
