Laboratory simulation is the only feasible way to achieve Martian environmental conditions
on Earth, establishing a key link between the laboratory and Mars exploration. The mineral …

The relationship among the curves of mass flow rate, temperature and pressure as a
function of time in an orifice pulse-tube refrigerator is analyzed to explain the previously …

Measurements of velocity oscillations have been made in order to understand the basic
refrigeration mechanism in typical pulse tube refrigerators. A hot wire probe, equipped with a …

A start-up behavior of a pulse tube refrigerator is experimentally investigated to gain a better
understanding of the basic refrigeration mechanism. Two typical types of pulse tube …

A new observation of the orifice pulse tube (OPT) cryocooler is proposed and analyzed on
the ground of the unified model of cryocoolers. The elementary temperature reduction …

A basic pulse tube refrigerator has been constructed with extensive instrumentation to study
the heat transfer characteristics of the heat exchanger experimentally under the oscillating …

A single stage linear Orifice Pulse Tube Refrigerator (OPTR) was designed, and tested. Gas
pressure, gas/wall temperature, heat load, phase shift, and frequency were measured and a …

A 3 valve-type pulse tube refrigerator optains its cooling effect from pressure drop by
releasing the part of the charged gas through hot end nozzle. The objective of this study is to …

Publisher Summary This chapter focuses on the radial temperature and velocity profiles of
oscillating flows in a pulse tube refrigerator to clear the differences of the performance …
