Abstract
We have constructed and investigated a linear, low frequency pulse tube system in the basic [BPT] and orifice [OPT] configurations with a three-way electro-mechanical valve. Prior to manufacturing, regenerator characteristics have been studied using a cellular model with repetitive cells in the asymptotic range of laminar boundary layer-dominated flow at relatively large (subcritical) Reynolds numbers. The ratio of heat transfer rate to throughput rate of the model system agrees in the order of magnitude prediction with screen data noting quantitative superiority of the cell system. We have determined for the basic and the orifice pulse tube frequencies at the minimum temperatures: 1 Hz for the BPT, 2 Hz for the OPT, both operating with air.
