Abstract

Thermoacoustic systems have been a focus of recent research due to its structural simplicity, high reliability due to absence of moving parts, and can be driven by low grade energy such as fuel, gas, solar energy, waste heat etc. There has been extensive research on both standing wave and traveling wave systems. Towards the development of such systems, simulations can be carried out by several methods such as (a) solving the energy equation, (b) enthalpy flow model, (c) DeltaEC, a free software available from LANL, USA (d) Computational Fluid Dynamics (CFD) etc. We present here the simulation studies of standing wave and traveling wave thermoacoustic prime movers using CFD and DeltaEC. The CFD analysis is carried out using Fluent 6.3.26, incorporating the necessary boundary conditions with different working fluids at different operating pressures. The results obtained by CFD are compared with those obtained using DeltaEC. Also, the CFD simulation of the thermoacoustically driven refrigerator is presented.

Experimental study and analysis on components of a thermoacoustic refrigerator and thermoacoustic prime mover

Conference Nohtomi, Makoto; Katsuta, Masafumi

A thermoacoustic refrigerator and a thermoacoustic prime mover, due to its simple structure, would serve as very desirable systems because thermoacoustic prime movers can be driven with the waste heat such as an exhaust gas from engines, and with heat from the nature such as sunlight and a geothermal heat. The thermoacoustic refrigerator and the thermoacoustic prime mover combined would serve as a perfect cooling system without moving parts, CFC's and HFC's. Thus this Thermoacoustic-driven Thermoacoustic Refrigerator will replace the previous paper compression refrigeration system. The authors set up the thermoacoustic refrigerator and thermoacoustic prime mover to investigate the fundamentalmore »« less
Wind driven prime mover

Patent Edmunds, W

A vertical axis wind driven prime mover has plural circumferentially spaced horizontal wind driven arms carried by a central hub which is attached to a central vertical axis rotational working shaft. Each wind driven arm carries multiple fixed blades or louvers which can extend horizontally or vertically on the arms. The louvers of each arm are constructed and arranged to act as impulse elements when the arm is moving with the wind on one side of the vertical axis machine and to form reaction motive elements when moving against the wind on the opposite side of the vertical axis machine.more »« less
Development of Thermoacoustic Sensors for Sodium-cooled Fast Reactors

Technical Report Heibel, Michael; Carvajal, Jorge; Ferroni, Paolo; ...

This Final Report refers to the project “Development of Thermoacoustic Sensors for Sodium-cooled Fast Reactor Systems”, which was led by Westinghouse Electric Company (Westinghouse) and carried out in collaboration with Argonne National Laboratory (ANL) and University of Pittsburgh. Thermo-acoustic Power Sensors (TAPS) are self-powered, wireless sensors envisioned for measuring key parameters, such as local temperature and neutron flux, in a nuclear reactor core. This project was intended to specifically investigate their applicability to Sodium-cooled Fast Reactors (SFR). TAPS are non-invasive (wireless) and passive (self-powered) devices. The passivity derives from their ability to use conditions that “naturally” exist in a nuclearmore »« less
Specific acoustic impedance measurements of an air-filled thermoacoustic prime mover

Journal Article Arnott, W; Bass, H; Raspet, R - Journal of the Acoustical Society of America; (United States)

Thermoacoustic heat engines can be used to produce sound from heat and to transport heat using sound. The air-filled prime mover studied is a quarter wavelength resonator that produces sound at nominally 115 Hz for a temperature difference of [Delta]T = 176 K. Specific acoustic impedance at the mouth of the prime mover was measured as a function of the temperature difference between the hot and cold heat exchangers. The real part of the impedance changes sign for sufficiently large temperature differences, indicating the possibility of sound production. The theoretically predicted radiation impedance of an open pipe was compared tomore »« less

Measurements with reticulated vitreous carbon stacks in thermoacoustic prime movers and refrigerators

Journal Article Adeff, J; Hofler, T; Atchley, A; ... - Journal of the Acoustical Society of America

Reticulated vitreous carbon has been successfully used as a stack material in thermoacoustic prime movers and refrigerators. It is a rigid glassy carbon material, with a porous spongelike structure. Test results indicate peak pressure amplitudes of up to 32{percent} in a prime mover, and refrigeration performance comparable to that of a traditional plastic roll stack. {copyright} {ital 1998 Acoustical Society of America.}
