Technical Effects of Air Cooled Blast Furnace Slag on Asphalt Mixtures

Air cooled blast furnace slag is a by product made of gradually air cooled molten blast furnace slag and is often stored in stockpiles near the iron mills and usually occupy a wide area around the iron mills. From this perspective the further use of these materials can have its own merits. Air cooled blast furnace slag can be used in asphalt mixtures because of their proper frictional propertie...

the role of detonation modeling on the calculation of fuel-air explosion (fae) blast properties

in this work the effect of the accuracy of a fae detonation modeling on the generated blast wave is investigated. first, a one-dimensional numerical simulation with a reduced chemical kinetics of c2h2-o2-ar, involving 25 elementary reactions, is used as the base model. the properties of the blast calculated with this model is compared with those of simpler models, the similarity solution of tay...

Numerical Investigation of Circular Plates Deformation under Air Blast Wave

In the current research the maximum deflection of circular plates made of AA5010 and AA1100 alloys under blast load was investigated. Shock waves were produced by exploding a spherical charge in different distances from the center of plates. The ABAQUS software uses conwep equation for blast loading analysis. It was found the results of these simulations have about 30% to 40% inaccuracy in comp...

Hot-air balloon explosion in the heart.

A 16-year old girl experiencing palpitations underwent elective transthoracic echocardiographic examination at a nearby clinic, which showed a 3-cm balloon-like, cystic structure, with inhomogeneous content, adherent to the atrial septum and anchored above the anteroseptal commissure of the tricuspid valve without evidence of flow from the aorta to the right atrium (Figure 1 A). On examination,...
