Abstract


Helical coil heat exchangers are popular because of compact structure with enhanced heat transfer coefficient by passive heat transfer enhancement technique. Due to these advantages helical coil tube heat exchangers are widely used in various applications like power plants, nuclear reactors, refrigeration and air-conditioning systems, heat recovery systems, chemical processing and food industries. The analysis of the helical coil heat exchanger with different operating and geometric parameters is presented in this paper. The analysis shows that both operating and geometric parameters are having influence on heat transfer characteristic. The analysis of heat transfer coefficient and Nusselt Number with respect to Reynolds number with different correlations and its signifence is discussed in this paper. The effect of geometric parameter on performance of helical coiled tube heat exchanger is also presented in this paper.
