“…The regenerator geometry was the stainless steel screen with the cold end at 80 K and the warm end at 300 K. The average pressure, pressure ratio at the cold end and the frequency of operation were 3.5 MPa, 1.3 and 120 Hz respectively. In 2017, Srikanth and et al [15] designed an IPTR that delivered 1 W cooling at 80 K and 100 Hz Frequency. Figure 2: The Thermoacoustic Stirling Heat Engine(TASHE) [22] Although the TASHE and the IPTR organized on the same phenomenon, called thermoacoustic technology, the TASHE had elapsed through different histories.…”

The Thermoacoustic Stirling Heat Engine(TASHE) designed by Backhaus, a device without moving parts which operates at a frequency of 85 Hz with an average pressure of 3 MPa that is capable of using sustainable energies, is applied to run an Inertance Pulse Tube Refrigerator(IPTR) with 1 W cooling power at 90 K. The coupling of these devices caused to eliminate all moving parts as well as miniaturizing the refrigerator to use for cooling superconducting magnets for MRI systems. A new method for the design of the IPTR performed by using numerical simulation of REGEN3.3. Moreover, to have a better vision of the overall configuration of IPTR and verify the Results of REGEN3.3, DeltaEC is used as an auxiliary software. Fortunately, both software results matched perfectly, and the performance of the IPTR was acoustically and thermodynamically ideal.
