چکیده
An experimental survey of CH absorption near the QojC?) and Qlc(7) lines of the {A2A (v=0) ♦ XZn (v=0» band was obtained at 2840°K, 0.2 atm using a remotely located cw ring dye laser source and a shock tube. Mixtures of methane and argon were shock heated to provide reproducible peak concentrations of CH, and narrow-line absorption was measured in repeated experiments with the laser set at different wavelengths. The spectral absorption data were interpreted with a theoretical model in order to verify the measurements and establish the sensitivity of this technique as an in situ absorption diagnostic for CH at 431.132 run (vac).

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 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...
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 کاملNumerical 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...
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...
