The iron and steel industry is a high-energy consumption high-pollution industry. Energy recovery in its process of great significance. Converter gas an important by-product the production. It difficult to take effective measures recover waste heat from converter due flammability. In this paper, new technology proposed based on by filled bulb regenerator. mathematical model transfer flow compou...

The chemical regeneration of granular activated carbon exhausted in a petrochemical wastewater unit was investigated. Gas chromatography and energy-dispersive X-ray spectroscopy demonstrated that spent activated carbon carries large types of organic and inorganic materials. Diverse chemical solvents were adopted in comparison with traditional chemical solvents and regeneration efficiency was in...

Telecommunication systems make use of optical signals to transmit information. The strength of a signal in an optical network deteriorates and loses power as it gets farther from the source, mainly due to attenuation. Therefore, to enable the signal to arrive at its intended destination with good quality, it is necessary to regenerate it periodically using regenerators. These components are rel...

An acoustic field spontaneously induced in a thermoacoustic prime mover consisting of a looped tube and resonator is determined through simultaneously measurements of pressure P and velocity U. A thermal efficiency of the thermoacoustic prime mover of this type has been reported to reach 30%. The measurements of the acoustic field in the present system revealed that a phase lead of U relative t...

Thermoacoustic functions are important parameters of one-dimensional codes used for the design of thermoacoustic engines. The thermal and viscous thermoacoustic functions allow the inclusion of three dimensional effects in one-dimensional codes. These functions are especially important in the regenerator of a thermoacoustic engine, where the thermoacoustic heat pumping occurs. Even though analy...

We present a novel class of reduced-order regenerator models that is based on Endoreversible Thermodynamics. The rest upon the idea an internally reversible (perfect) regenerator, even though they are not limited to description. In these models, temperatures working gas alternately streams out regenerator’s hot and cold sides defined as functions state matrix. matrix assumed feature linear spat...

In an optical network a signal can only travel a maximum distance of dmax before its quality deteriorates to the point that it must be regenerated by installing regenerators at nodes of the network. As the cost of a regenerator is high, we wish to deploy as few regenerators as possible in the network, while ensuring all nodes can communicate with each other. In this paper we introduce the gener...

The features of classical thermodynamic cycle of Stirling engine considering the periodic reciprocal motion of working body through the regenerator have been analyzed in this work. The possibility of satisfactory functioning of modified engine without regenerator with unidirectional pulsating motion of the working body in reсuperative heater and cooler has also been proved. The characteristic f...
