Abstract Influence of area ratio (AR) on main performance parameters solar chimney power plants (SCPPs) is investigated through a justified 3D axisymmetric CFD model. Geometric characteristics Manzanares pilot plant (MPP) are taken into consideration for the numerical AR varied from 0.5 to 10 cover both concave and convex (convergent divergent) designs. Following accuracy verification results p...
The effect of brickworks emissions on heavy metal content of soil and plants around the brick kiln chimneys was studied in the year 2006. Two brick kilns (A and B) about 600 m away from Ring Road at SufaidDheri on southerrn side of Peshawar, Pakistan were selected for this study. The two bricks kilns were North-South to each other with 300 m distance in between, such that South direction from b...
Experiments study large-scale pattern formation during the growth of ammonium chloride (NH4Cl) from solution in a thin (Hele-Shaw) geometry. In particular a solid-liquid mixture ("mushy layer") forms in which growing solid NH4Cl crystals form a solid network interspersed with liquid. There are different ways that the mushy layer can be formed, however. If the cell is heated from below and coole...
OBJECTIVES We sought to analyze the collected worldwide experience with use of snorkel/chimney endovascular aneurysm repair (EVAR) for complex abdominal aneurysm treatment. BACKGROUND EVAR has largely replaced open surgery worldwide for anatomically suitable aortic aneurysms. Lack of availability of fenestrated and branched devices has encouraged an alternative strategy utilizing parallel or ...
[1] We examine the characteristics of the initial stage (IS) in object-initiated lightning derived from current measurements on the Gaisberg tower (100 m, Austria), the Peissenberg tower (160 m, Germany), and the Fukui chimney (200 m, Japan) and their counterparts in rocket-triggered lightning in Florida. All lightning events analyzed here effectively transported negative charge to ground. For ...
