The main aim of this work is to develop a straightforward computer code for transient response of crossflow heat exchangers with both fluids unmixed and finite wall heat capacity. The transformed temperatures of the core wall and both fluids expressed in the form of power series are specialized to describe arbitrary time varying inlet temperature of the primary fluid. These transformed temperatures expressed in the form of power series are so regular that they are easily written in a computational program. Moreover, it is not difficult to invert the transformed temperatures to the physical quantities by using the numerical inversion method of Honig and Hirdes. For this problem, the method has considerable saving in the computer time because of a fast rate of convergence.
