Three dimensional numerical computation of the flow field in a pulse tube

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A physical and numerical model of the pulse tube in the pulse tube refrigerator has been set up in this paper. Three-dimensional computation of a compressible and oscillating flow field in pulse tube was numerically investigated using a self-developed code. The distributions of the velocity and pressure waves and the velocity vector in the pulse tube were provided in this paper. The velocity wave near the hot end of the pulse tube lags behind that near cold end, and at the some cross section of middle part of the pulse tube the direction of the axial velocity reverses.
