Thermoacoustic heat engines can convert thermal energy into acoustic power or vice versa
with advantages of high reliability and low environmental impact. In conventional …

Thermoacoustic technology is a promising approach for environmentally-benign, low-cost
heat pumping. Herein, we present a theoretical investigation on phase-change …

Ground source heat pump, due to high coefficient of performance (COP) and use of low-
temperature thermal energy source, is one of the best technologies to use renewable energy …

Introducing a phase-change component to thermoacoustic regenerators or stacks increases
the complexity of the thermoacoustic conversion process, and currently the analysis of …

Exergoenvironmental analysis is used to assess system performance from an environmental
point of view. The analyses' guiding principles are formed based on evaluations of the …

Abstract Phase-change ('wet') thermoacoustic engines offer significant potential for efficient
and clean conversion of low-grade heat. Previous work has demonstrated the effectiveness …

Thermoacoustic devices, in which heat fluxes and pressure waves are converted from one to
the other, are a promising class of energy conversion, particularly as heat-driven heat …

Thermoacoustic engines are devices in which heat is converted into acoustic oscillations,
which can be tuned to mimic the thermodynamic cycle executed by mechanical motion such …

In this work, a new explanation on an old idea to enhance the Stirling engine, ie, the
evaporative (two-phase two-component) Stirling engine, has been provided through …

Thermoacoustic heat pumps (TAHPs) can be used for heating and/or cooling purposes.
Current designs of travelling-wave TAHPs normally employ a single acoustic driver and rely …
