Abstract

Reformulating the theory of pulse-tube operation from the ideal-gas situation to a real gas, changes the properties drastically. The nonideal-gas properties have a profound effect on the energy balance in the regenerator and on the expression for the cooling power. The temperature profiles in the regenerator are strongly affected by the thermal properties of the fluid. We show that, for large flow rates, the dissipation in the regenerator is proportional to the flow rate and cannot be reduced by reducing the thermal conduction coefficient or the regenerator geometry.
