In this paper, design analysis of a shell and tube heat exchanger with a phase change material on the shell side cooled by a fluid passing through the tube is presented. A simple closed form design for two-dimensional freezing is presented. Results from the present analysis are shown to agree within two per cent of the involved numerical solutions to the problem. The design parameters, optimized for minimum pressure drop, power requirement and critical net work are presented for evolution of systematic design criterion. Results in terms of frozen thickness, coolant bulk temperature, tube wall temperature and extracted energy, as function of coolant Stanton number and Biot number are discussed. A generalized dimensionless closed form design equation in terms of Stanton number, Biot number and Stefan number are recommended for effective sizing of a shell and tube heat exchanger for latent heat storage.
