ABSTRACT
Thermo acoustic have been known for over years but the use of this phenomenon to develop engines and pumps is fairly recent. Thermo acoustic refrigeration is one such phenomenon that uses high intensity sound waves in a pressurized gas tube to pump heat from one place to other to produce refrigeration effect. In this type of refrigeration all sorts of conventional refrigerants are eliminated and sound waves take their place. All we need is a loud speaker and an acoustically insulated tube. Also this system complet ....etc

Introduction to CWR

The CWR is a rotary forming process, consists
of the forming of forging by means of wedge-shaped tools that are fixed on the mill rolls with the same rotary direction.
In CWR process, there are five stages in the work piece deformation process corresponding to five zones of the wedged tool geometry, i.e., knifing, guiding, stretching, shaping, and sizing.

Knifing zone, is ....etc

Thermoacoustic Refrigerator

In 1987 an international group of scientists and Government Officials established the Montreal protocol, an agreement to control the use and release of CFC and to schedule a time frame for eliminating their production. This agreement is a historic step in the on going process of building consensus regarding environmental impact of CFC. Both the Montreal protocol and provisions for 1990 clean Air Act specify schedules for phasing out CFC production by year 2000.
This forced a new wave of research and development i ....etc

Thermoacoustic Stirling Engines
Abstract:
Sound waves in thermoacoustic engines and refrigerators can replace the pistons and cranks that are typically built into such machinery. Over the past two decades, physicists and engineers have been working on a class of heat engines and compression-driven refrigerators that use no oscillating pistons, oil seals or lubricants. These so-called thermoacoustic devices take advantage of sound waves reverberating within them to convert a temperature differential into mechanical ene ....etc

Thermoacoustic Refrigeration



How it works

Moving coil Loudspeaker
Inside 2 magnets with metal coil between them, current is induced causing coil to move
Creates sound waves up to 200 dB!
Resonator where gas cooling and compression take place
Uses inert gas, commonly Helium
Stack
Series of small parallel channels through which pressure and velocity of waves change
In between the heat exchangers
Heat Exchangers
Hot heat exchanger to remove excess heat
Cold heat exch ....etc

Microelectromechanical systems
Microelectromechanical systems (MEMS) (also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems) is the technology of very small mechanical devices driven by electricity; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as ....etc

This project was undertaken at the penn state uty. thermoacoustic refrigeration at high amplitudes has married a high power acoustic driver (up to 100 W of acoustic power) to the resonator of the STAR(The Space Thermoacoustic Refrigerator) refrigerator

Overview of the device
The STAR has the ability to move about 5 Watts of heat and exhibited a peak coefficient of performance relative to Carnot about 20%.

The drivers for this refrigerator are 55% electric-to-acoustic efficient.The Shipboard Electronics Thermoacoustic Cooler (SE ....etc
