DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM

ABSTRACT
Cooling effect at one end of a hollow tube with a pulsating pressure in the inside gas, was first observed by Gifford and Longsworth in early sixties. This marks the inception of one of the most promising cryogenic refrigerators known as 'pulse tube refrigerator' (PTR). Cryogenics is the science of low temperature. Cryogenics refers to the entire phenomenon occurring below -150°C or 123K. Cryogenic engineering involves the design and development of ....etc

Abstract A commercial Computational fluid dynamics (CFD) software package Fluent 6.1 is used to model the oscillating flow inside a pulse tube cryocooler. In this paper analysis of orifice type pulse tube refrigerator (OPTR) systems operating under a variety of thermal boundary conditions are modeled at different frequencies. The compressor us ....etc

The importance of refrigeration i s fundamental in meeting the United Nations Millennium development goals, particularly for t h e millions of the world’s poor living in the t r o p i c s . dissigno set out determine the physically v i a b i l i t y to produce sufficient refrigeration to make ice from a Ranque-Hilsch Vortex tube. The base o b j e c t i v e s were, 1 kg of ice produced per work cycle, cost l e s s than $500 installed, minimal moving parts, only use renewable energy, & limit impact to t h e environment.
