Over the past decades, industrial sector has been trying to improve use of resources and environmental impact they create. Significant work done in compressed air systems. However, there is still much room for improvement. The focus this study on a new approach energy efficient filtration. This involves installation different filter configurations that enable lower pressure drop, instead conven...

A tool (TEAP) to evaluate in real-time and operational mode the air quality produced by industrial plants (power plants also) has been developed based on the third generation of air quality modelling systems. The system uses the non-hydrostatic mesoscale meteorological model MM5 (PSU/NCAR, USA) and the air quality modelling system (transport and chemistry) CMAQ (Community Multiscale Air Quality...

An efficient and sufficiently power dense air compressor/expander is the key element in a Compressed Air Energy Storage (CAES) approach. Efficiency can be increased by improving the heat transfer between air and its surrounding materials. One effective and practical method to achieve this goal is to use water droplets spray inside the chamber when air is compressing or expanding. In this paper,...

A series of one-dimensional studies is presented to reveal basic aspects of momentum and energy transfer to plates in air blasts. Intense air waves are initiated as either an isolated propagating wave or by the sudden release of a highly compressed air layer. Wave momentum is determined in terms of the energy characterizing the compressed layer. The interaction of intense waves with freestandin...

There is a wide variety of gripping devices with various parameters at the present stage development robotics. However, existing literature about power characteristics pneumatic does not provide any analysis different types input other than supply pressure and flow characteristics, whereas completely determine technical industrial robots. In particular, for grippers, play crucial role in their ...

Flexible combined cooling, heating, and power (CCHP) systems are effective in integrating wind sources. As an attractive, clean, large-scale energy storage technique, the advanced adiabatic compressed air (AA-CAES) can store generate both electricity also provide cooling during expansion under certain conditions. Although AA-CAES has immense potential multi-energy supply systems, CCHP dispatch ...
