【Abstract】 In this paper, a theoretical model and its controlling equations are set up for the connecting hose of an 80K split-Stirling cycle cryocooler. By introducing the method of characteristics, the inlet (outlet) conditions were dealt and the governing equations are solved by numerical method. The simulated results are compared with the experimental one, and they are in good agreement.更多还原
