      Contributed Oral Presentation

      Vuilleumier (VM) type pulse tube cooler is a novel kind of cryocooler to obtain liquid helium temperature which had been experimentally verified. However, the efficiency is not satisfying. Based on previous work on a low pressure ratio system, a numerical investigation that explore the effect of high pressure ratios on refrigeration performance is presented in this paper. The research system...
