Propagation of shock waves through a set of plate barriers is studied numerically. It is found that the studied barrier sets are very effective in attenuating transmitted shock waves. All transmitted shock waves through the proposed barrier sets are

The starting flow process in a two-dimensional planar wedge nozzle is studied numerically. The flowfield is solved using several turbulence models. Good agreement with experimental interferograms is achieved when using the Reynolds stress model. Solv

Flows in which shock wave interact with a rigid boundary are found in many engineering applications and therefore draw a lot of attention during the past seven decades. The rigid boundary may have different geometry, a building where an explosive air

Results of experiments investigating shock wave reflections from wedges having sawtooth roughness of 0.1 mm, 0.2 mm, 0.8 mm, and 2.0 mm are presented. Observations based on direct shadowgraph diagnostic revealed that for wedges whose inclination angl

Consider a shock tube configuration with a sharp transition between a wide driver segment and a much narrower driven segment. The flow commencing upon the rupture of the diaphragm that separates the two segments is studied both numerically and by ana

The current paper discusses the shock standoff distance over spheres in unsteady flows. In a ballistic range, spherical projectiles were launched into atmospheric air for wide transonic ranges of projectile Mach numbers. We visualized shock standoff

Experimental studies conducted during the 70s and 80s of the previous century are numerically simulated. We examine a horizontal duct with a vertical branch having a circular cross section whose diameter is 5 cm. These experiments were conducted by t
