โœฆ Synopsis

Along with the advances of pulse tube refrigeration, there is a pressing demand for a theoretical model which not only reveals the essentials of the internal physical processes, but also can be used for reliable practical design. In this paper, we consider the thermal and viscous influences of the pulse tube wall and propose the concept of a thermal viscous layer in the pulse tube, on which the compound pulse tube model is based. The principal losses of cooling, including regenerator inefficiency loss and solid conduction loss, are then taken into account. Adiabatic calculation of the directly coupled compressor is also included in the theoretical model.

The heat input towards the cold end of a pulse tube refrigerator is studied using combinations of two regenerators and two pulse tubes of different lengths. The temperature gradient in the pulse tube or regenerator is altered by changing the length. Changing the regenerator length produces almost no
