Thermoacoustic analysis of a pulse tube refrigerator

Phasor Analysis of Two-stage Gm-type Pulse Tube Refrigerator

A two-stage pulse tube refrigerator (PTR) is the simplest version of a multistage pulse tube refrigerator. A two-stage Gifford-McMahon (GM) has been used for nearly all of the cryopumps. The phasor analysis of the Gifford-McMahan (GM)-type pulse tube refrrigerator (PTR) have not explained detail in the earlier study. In the present work, a detailed mass flow, enthalpy & phasor analysis for a tw...

Thermal modeling and performance analysis of a thermoacoustic refrigerator.

A heat-driven thermoacoustic refrigerator has been designed and tested. A detailed thermal model of the device is presented. Energy balances within the system are discussed using external, heat exchanger, and stack control volumes in order to clarify the relationships of work and heat fluxes below and above onset. Thermal modeling is discussed as a tool for performance analysis as well as for d...

Optimizing the Design of a Thermoacoustic Refrigerator

Numerical Analysis of Transport Phenomenon Inside a Pulse Tube Refrigerator Coupled with Fuzzy Logic Controller

This research article illustrates a numerical study of single stage coaxial as well as inline Inertance-Type Pulse Tube Refrigerator (ITPTR). In this present work a computational fluid dynamic (CFD) approach has been adopted for numerical simulation purpose. The detail analysis of cool down behaviour, heat transfer at the cold end and the pressure variation inside the whole system has been carr...

The Reality of a Small Household Thermoacoustic Refrigerator

This paper discusses the thermoacoustic refrigeration cycle and how it can be applied to real world uses, particularly its use in household refrigeration systems. The commercial viability of this technology is determined by comparing it to a vapour compression system. The paper has two goals: to determine practical applications where thermoacoustic refrigeration may prove a strong rival to curr...
