The operating behavior of an Oxford cryocooler has been modelled using the SIMPLER algorithm of Patankar, and the implicit correction scheme by the present authors, to solve the balance equations.

Kornhauser and Smith’s complex Nusselt number correlation for heat transfer is used in the compression and expansion spaces. Armour and Cannon’s friction factor and Kays and London’s heat transfer correlations are used in the regenerator and connecting pipe. However it has been necessary to modify these correlations using correction factors, which take account of the effects of oscillating flow, constructed on the basis of experimental data. Comparisons with measurements show that the correction correlations can be used successfully to evaluate the friction force and heat transfer under operating conditions and that the model can be used to predict the operating behavior of the cryocooler.
