Transient analysis of a cross flow heat exchanger subjected to a step increase in temperature of the minimum capacity rate fluid was considered. Predictions obtained using an implicit central finite difference method were presented. The influence of varying grid sizes and time steps sizes on these approaches was addressed. A parametric study was conducted by varying the dimensionless parameters governing the transient response of heat exchanger over a representative range of values.
