Polymer hollow fibre shell and tube heat exchanger for liquid-liquid applications

Paper provides comparison of different heat exchangers which differ in length, number and material of fibres. It also deals with an influence of various arrangement of fibres on the efficiency of heat exchangers (HEs). These have a potential to be used in low temperature and low flow rate applications. Number of Shell and tube Polymer heat exchangers were fabricated with various polymers and tested. The heat transfer performance and pressure drops were studied with hot water at 60 and 80 degrees C flowing through the shell side. It was observed that heat transfer rates (up to 36 kW), and the overall heat transfer coefficients of these devices were 647-1314 W/ (m2K) for water-water applications, and pressure drops are competitive to conventional metal Shell and Tube heat exchanger.Papers presented at the 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Portoroz, Slovenia on 17-19 July 2017 .International centre for heat and mass transfer.American society of thermal and fluids engineers
