Exact transient solutions of parallel-current transfer processes are obtained by the use of the Laplace transformation. Solutions are valid for a finite or an infinite transfer zone. The solutions are verified with steady-state solutions. Exact transient solutions of this study are applicable to liquid-to-liquid and liquid-to-gas heat exchangers in which the thermal capacitance of the core is negligible (zero) compared to the thermal capacitance of the stepped liquid contained in the exchanger.
