Experimental analysis of shock waves turbulence in contractions with rectangular sections
Formation of shock waves has an important role in supercritical flows studies. These waves are often occurring during passage of supercritical flow in the non-prismatic channels. In the present study, the effect of length of contraction wall of open-channel for two different geometries (1.5 m and 0.5 m) and fixed contraction ratio was investigated on hydraulic parameters of shock waves using ex...
متن کاملExtracorporeal shock waves act by shock wave-gas bubble interaction.
The effect of extracorporeal shock waves on hemoglobin release from red blood cells was recently found to be minimized under minute static excess pressure. It was proposed that this can be explained by shock wave-gas bubble interaction. We substantiated this further by two experiments by applying shock waves to suspended human RBC in a lithotripter at a lower frequency (1 pulse every 5 s) and b...
متن کاملبررسی تغییرات ایجاد شده در آنزیم های کبدی پس از درمان سنگ های کلیوی به وسیله سنگ شکنی خارج اندامی با امواج ضربه ای (گزارش کوتاه)
Background and purpose: Extracorporeal shock wave lithotripsy changed the treatment of renal stones. Beacause the widespread usage of ESWL (extra Corporeal shock wave lithotripsy) in the treatment of the Urinary tract stones, the effects of these waves on the surrounding tissues are not compeletly understood and it is the origin of so many studies. Materials and methods: In this prospectiv...
متن کاملStudy of Parameters Affecting Separation Bubble Size in High Speed Flows using k-ω Turbulence Model
Shock waves generated at different parts of vehicle interact with the boundary layer over the surface at high Mach flows. The adverse pressure gradient across strong shock wave causes the flow to separate and peak loads are generated at separation and reattachment points. The size of separation bubble in the shock boundary layer interaction flows depends on various parameters. Reynolds-averaged...
متن کاملAn Experimental Study of Shock Waves Resulting from the Impact of High Velocity Missiles on Animal Tissues
The spark shadowgram method of studying shock waves is described. It has been used to investigate the properties of such waves produced by the impact of a high velocity missile on the surface of water. The method can be adapted for study of behavior of shock waves in tissue by placing the tissue on a water surface or immersing it in water. Spark shadowgrams then reveal waves passing from tissue...
متن کاملTransonic and Supersonic Overtaking of a Projectile Preceding a Shock Wave
In this paper, two-dimensional and axisymmetric, time dependent transonic and supersonic flows over a projectile overtaking a moving shock wave are considered. The flow is simulated numerically by solving full time averaged Navier-Stokes equations. The equations are linearized by Newton approach. The roe’s flux splitting method, second order central difference scheme for the diffusion terms, an...
