Hybrid model of displacer pulse tube refrigerator
朱 紹偉, 郭 志敏 （同済大）
Abstract:CFD simulation of displacer type pulse tube refrigerator is an effective method, but it causes a lot of computing time for one case even by high performance computer, which is hard to get group results quickly unless much computing resource is supplied. A hybrid model with isothermal and adiabatic is introduced, which can be simply calculated by Excel. It is not only can be a pre-selected method to supply basic data for CFD simulation to save computing resource, but also can be a preliminary method for pre-design of displacer type pulse tube refrigerator.
