Analysis of gasdynamics in Pressure Wave Refrigerator
Details
The pressure wave refrigerator (PWR) is the wave-machine to refrigerate the gas with intermittent expansion waves. Due to the simple structure. and robustness, PWR may have many potential applications if the efficiency becomes competitive with the existing alternative devices. In order to study deeply the mechanism in PWR and practice an industry utilizing, a unique compact PWR facility was set up in SWRC, Institute of Fluid Science, Tohoku University. The performance of the PWR facility is evaluated and the effect of major operation parameters, such as the rotational rate of gas distributor, the length of expansion tubes and some configuration parameters are discussed in the paper Some theoretical considerations to improve the PWR efficiency are also given.
