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

Abstract:
Given an undirected, unweighted graph G = (V, E), the minimum vertex cover problem is a subset of whose cardinality is minimum subject to the premise that the selected vertices cover all edges in the graph. There are various other algorithms that follows heuristic based approaches, but using those approaches we are not able to find optimal solution always in the same manner Greedy algorithms solves the same problems but some problems have no efficient result, but up to a certain extend the Greedy algorithm ....etc

The vortex tube was discovered in 1930 by Georges Ranque, a French physics student, was experimenting with a vortex-type pump he had developed when he noticed warm air exhausting from one end, and cold air from the other. Ranque soon forgot about his pump and started a small firm to exploit the commercial potential for this strange device that produced hot and cold air with no moving parts. However, it soon failed and the vortex tube slipped into obscurity until 1945whenRudolphHilsch, a German physicist, published a widely read scientific paper ....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

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
