Experimental, Analytical and Numerical Investigation of Double Pipe Parallel Flow Heat Exchanger

The computational fluid dynamic are a powerful method to study heat and mass transfer from the many years. Applications of heat exchanger include cogeneration, condensation in power plants, waste heat recovery etc. Heat exchanger is a process of decreasing the energy consumption by reducing the thermal energy lost to the sink. Due to reducing the thermal losses the performance of the overall system will be increase. In this work an experimental, analytical and numerical model has been developed for analysis of heat transfer co-efficient foe parallel flow heat exchanger. The numerical model has been validated to the experimental data. The double pipe parallel flow heat exchanger length, inner pipe diameter and outer diameter of pipe are 2.5 m, 0.0107 m and 0.0254 m respectively. Hot water is flowing in inner pipe and temperature hot water is 400C, cold water is flowing in outer pipe and temperature cold water is 150C. The cold water mass flow rat has been maintain constant and hot water mass flow rate has been change at different Reynolds (2000 to 9000) is used for find out the heat transfer co-efficient at fixed parameter like length of pipe, diameter of pipe, fluid (water), material of pipe (cupper) and inlet temperature.
