Thermal Analysis of A Thermo Acoustic Cryocooler

Abstract

Thermo acoustically driven pulse tube cryocoolers are gaining significant interest in the recent time due to the key advantage of complete absence of moving components for the entire system.The geometrical parameters are the stack length, the stack position, the resonator length. This work deals with the 2 - D computational fluid dynamics analysis of flow in a Thermoacoustic Cryocooler. The software used for this purpose are GAMBIT and FLUENT. The 2 D model of the parts of the Cryocooler are made by GAMBIT and analysis are to be carried out by FLUENT. The models are first generated using the data and then are meshed and then various velocity and pressure contours are drawn and graphed in this paper to analyze the flow through the cryocooler.
