Performance Evaluation for the Tube in Tube Heat Exchanger by Wire Mesh Technique

This experiment provide method for increasing tube-in-tube exchanger performance. The tube-in-tube heat exchanger is designed in order to study the process of heat transfer between two fluids through a solid partition. It will be designed for a parallel flow as well as counter-flow arrangement. The logarithmic mean temperature difference (LMTD) method of analysis is adopted. Water will be used as a working fluid for the experiment. The parameter required to find out the effectiveness of the heat exchanger will be arranged in this setup such as the inlet and outlet temperature of the hot and cold fluid, flow rate of the fluid power etc. The modified wire mesh tube in tube will be replaced for the ordinary tube in tube so the surface area is increased so maximum heat will exchange from hot side to the cold side. This will be proved by calculation of the LMTD, Heat transfer coefficient and temperature difference. The experimental procedure carries tests for both ordinary heat exchanger and wire mesh heat exchanger. Arrangement will be made such that in one set we can achieve the both parallel and counter flow by simply opening and closing of the valve shown in the process of this whole setup. This set up is used for comparing the Logarithmic mean temperature difference, heat transfer coefficient, the effectiveness and the temperature difference for the modified wire mesh heat exchanger & with the ordinary Heat exchanger. From the results, it is observed that the overall heat transfer coefficient and effectiveness is increased for Wire Mesh heat exchanger as compared to the ordinary tube heat exchanger.
