Numerical Analysis in a Thermoacoustic Cryocooler

Abstract

This project deals with the computational fluid dynamics analysis of flow in a Thermoacoustic Cryocooler showing the comparison between a straight tube and a curved tube resonator. This involves with the two dimensional analysis of flow through of Cryocooler having radial inlet and axial outlet. 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 to be drawn and graphed in this paper to analyze the flow through the cryocooler. Various graphs indicating the variation of velocity, pressure and temperature along the stream length of the turbine are given.
