Numerical study on the working performance of a G-M cryocooler with a mechanically driven displacer

Numerical simulation and exergy analysis of a single-stage GM cryocooler

“…In 2015, Xu and T. Morie [ 14 ] used the method to simulate the displacement of displacer, and proposed a novel scotch yoke which can enlarge the expansion cycle, while shorten the compression cycle, the experiment indicated that the cooling power of the first stage was increased by 10% with the new scotch yoke. In 2017, Zhi et al [ 15 ] analyzed the performance of a single-stage GM cryocooler made by SHI through CFD simulation. SST k-ε model and PISO principle were used for turbulence calculation and pressure-velocity coupling separately, the pressure boundary conditions were given according to the experimental data.…”
