hai sir,
Iam venkatanarayana nathi studying B-Tech final year in mechanical engineering.I want the above seminar topic detailed report(seminars title is PULSE TUBE REFRIGERATOR).Sir have done a mini-project on refrigeration in first semister,and now I want give a seminar my interest is in refrigeration,so I need the above seminar details and I donot know any thing about this pulse tube refrigerator,so I expect your reply for my mail .any how Iam feeling great to have an oppurtunity to recieve some information from you

Thank You,, ....etc

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 system ....etc

ppt working principle of pulse tube refrigerator

Abstract

The working fluid for the pulse tube refrigerator is Helium, which is non-toxic to humans and harmless to the environment. The Pulse Tube Refrigeration unit offers a viable alternative to units that currently require CFC and HCFC working fluids. Pulse Tube Refrigerators can be operated over wide range of temperatures. These units can be used in numerous space and commercial applications, including food freezers freeze dryers. It can also be used to cool detectors and electronic devices ....etc

Department of Mechanical Engineering, NIT Rourkela-769008, Orissa



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 used ....etc
