1 Abstract-The present paper presents an overview of the main characteristics of a novel kind of solar thermal application called solar chimney power plant. It is a technology of electric power generation using solar energy by employing basic physics that when air is heated it rises. The created updraft can be used to turn a turbine placed at an appropriate position within a tall chimney to gen...

PURPOSE To share our hybrid endovascular experiences using chimney or sandwich stent grafts for acute aortic arch pathologies. METHODS Hybrid procedures for a distal aortic arch aneurysm and an ascending anastomotic aortic aneurysm rupture were reported. Right to left common carotid and left axillar artery bypasses were located. Covered stents were inserted into the inominate artery, with the...

Evolution in the endovascular era has influenced the management of aortic arch pathologies. "Chimney" or "snorkel" graft technique has been used as an alternative in high risk patients unfit for open repair. We reviewed the published literature on the chimney graft technique for preservation of the supra-aortic branches in order to provide an extensive insight of its feasibility and efficacy an...

A solar chimney is designed and tested to pump outside air through an underground cooling tube during summer for building cooling. Both theoretical analysis and experimental results show that the solar chimney can be used to power the underground cooling system during daytime without use of electricity. This paper presents the theoretical design principals of the solar chimney, detailed experim...

The thermal impedance Zth j has been measured for the junction of a transistor mounted on a cooling fin. The setup was put inside a chimney in order to enhance the natural convection cooling. From the thermal impedance Zth j the influence of the chimney on the reduction in thermal resistance Rth Zth j 0 is clearly visible. A maximum improvement of almost 20% has been observed experimentally. Me...

The article calculates pressure losses due to friction and local resistance, which allows you determine the total in chimney. For normal operation of gas installations, conditions must be created under a vacuum is at exit points combustion products. task removing products includes determining cross sections chimneys connecting pipes.

The current global environmental trend is that the world has agreed to go towards net zero emissions. Consequently, waste-producing-industries must comply with these provisions achieve mission of sustainable development and green production, including cement industry. This study aims investigate factors affect performance Electrostatic Precipitator (EP) as a dust collector in grinding raw mater...
