Abstract
An optimize result of the single stage iterance tube pulse tube refrigerator (ITPTR) has been found by the use of a computational fluid dynamic (CFD) solution method. A well CFD solution software FLUENT is used for solution purpose. A number of case has been solved by changing the pulse tube length by taking diameter constant out of which it is found that a length of about 125mm at which the minimum temperature is achieved at cold heat exchanger end of 58K. The variation in any parameter of ITPTR will affect the cooling temperature that may be the length or diameter of pulse tube or inertance tube or change in operating frequency but it is essential to achieve lower temperature than till date achieved by same method. So for optimization purpose we take the length of pulse tube length as the varying Para-meter and the operating frequency 34Hz, pulse tube diameter 5mm remains constant. To get an optimum parameter experimentally is a very tedious for iterance tube pulse tube refrigerator job so the CFD approach gives a better solution which is the main purpose of the present work.
