Of his final project, the 'air-operated thermoacoustic
cooler', he says: "Thermoacoustics
utilise standing waves to generate periodic compression and expansion cycles, providing the thermodynamic mechanism to facilitate heat transfer.
The team from Purdue University and the University of Notre Dame in Indiana developed a theoretical model showing that thermoacoustics
can occur in solid materials.
Previous numerical studies with regard to thermoacoustics
have mostly adopted control volume and finite volume methods.

as an Alternative Technology for Waste Heat Recovery in Automotive and (Heavy) Duty Applications", 24th Aachen Colloquium Automobile and Engine Technology.
The amount of recoverable exhaust gas enthalpy of a system based on thermoacoustics
is limited by the hot-side temperature of the thermal module.
Aside from teaching, Abdel-Rahman has also devoted time to his research, specifically focusing on thermoacoustics
MICROWAVE RADAR AND MICROWAVE-INDUCED THERMOACOUSTICS
Flashback can be caused by (i) boundary layer flame propagation, (ii) turbulent flame propagation in the core flow, (iii) thermoacoustics
, and (iv) upstream flame propagation of coherent vortical structures [7, 9-11].
imaging is a hybrid modality which capitalizes on the contrast of microwave imaging combined with high resolution associated with ultrasound imaging.
Enter Steve Garrett of the Pennsylvania State University, a specialist in the science of thermoacoustics
who had been working as Scientific Adviser to the US State Department's South-East Asia bureau.
The following technologies were selected for initial consideration for the alternative cooling technologies: thermoelectrics, magnetocalorics, thermoacoustics
and the Stirling cycle.
Environmentally and socially conscious Ben & Jerry's Ice Cream has unveiled a prototype of a point-of-sale ice-cream freezer that runs on thermoacoustics
. The freezer compresses helium gas instead of harmful CFCs, HFCs or other chemicals, and was developed in conjunction with Penn State's Applied Research Laboratory, which holds a patent on the eco-friendly chiller technology.
