ct of variation of orifice area on refrigeration power:
Refrigeration power is affected in the same manner as that of the input power as in fig.4.3. It increases gradually with cross sectional area and remains constant and decreases slightly. The stray points are due to approximations made in the program. Effect of variation of orifice area on refrigeration power/mass flow:
Refrigeration power/mass flow rate increases with cross sectional area of orifice and reaches a maximum point and decreases as shown in fig. 4.4

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 is having dual opposed piston arrangement. The simulations are done at different frequencies with helium as working fluid. The simulated OPTR consists of a compressor (dual opposed pi..................[:=> Show Contents <=:]

ube. So heat is pumped from the cold end to the hot end in relays, which provides a certain capacity of refrigeration at the cold end while the hot end is maintained at room temperature by displacing heat to the environment.
1.5.2 Enthalpy Flow Theory.
While the surface heat pumping theory examines the physical behavior of one gas element, the enthalpy flow theory proposed by R.Radeburg soon after the appearance of the orifice pulse tube refrigerator studies the time-averaged thermodynamic effect of the pulse tube as a control volume.
Consider a cross section of pulse tube, for an ideal gas..................[:=> Show Contents <=:]

t engines, heat pumps and refrigerators. Whereas typical engines and refrigerators have different moving parts Thermoacoustic engines and refrigerators have almost a single flexing moving part (loud speaker) with no sliding seals.
In thermoacoustic primemovers heat flow from a high temperature source to a low temperature sink generates acoustic power (Which may be converted into electric power using a transducer). In thermoacoustic heat pumps and refrigerators acoustic power is used to pump heat from a low temperature source to high temperature sink.
Thermoacoustic devices may be of practica..................[:=> Show Contents <=:]
