... swirling separator, incorporating a central body, was designed for the numerical investigation, using commercially available software packages-FLUENT. The behavior of gas dynamic parameters is analyzed under conditions of separation in the region of shock wave and behind it. The basic parameters of gas...

.... The underwater shock wave is treated as a one-dimensional step-exponential pressure wave which propagates through the water that simulated using acoustic fluid element in ABAQUS/Explicit. The cavitation effect can be captured using the pressure criteria. The results obtained are compared with those obtained...

... This research is an experimental study on the settling process. Major topic is focused on the transition between gravitational settling and hindered settling, formation of shock wave, and settling behaviors at different water conditions. An array of Optical Backscatter Sensors (OBS) was used...

... to discontinuities (contact dis- continuities or shock waves). Shock formation has been con- sidered in the pioneering work of Lax (1964). While it is well established for one-fluid flows, it is much less developed for two-fluid flows. We consider a planar shock wave arriving perpendicularly to a wall, then hitting...

... The tsunami wave can be forced to break as a shock wave, annihilating her energy due to high intensity turbulence. This shockwave is created intentionally by a sea-bed sill, simulating an artificial steepening of the original sea-bed. The main advantage of the shock wave is that she conveys...

... ABSTRACT Dynamic fracture analysis and its response by shock wave caused by the non-contact underwater explosion are significant in the design of reliable marine vessels. In the USA navy, it is regulated to conduct the shock test of the marine vessels under explosion conditions...

..., an appropriate simulator needs to be built. This simulator is required to create shock waves on a operator located in a centrifuge (as shown in Fig. 1). Because the analysis is based on the effect of resonance, the waves which are generated need to be as "pure" and as "plane" as possible. Existing shock wave...
