The effect of distributed bubble nuclei sizes on shock propagation in dilute bubbly liquids is computed using a continuum two-phase model. An ensemble-averaging technique is employed to derive the statistically averaged equations and a finitevolume method is used to solve the model equations. The bubble dynamics are incorporated using a Rayleigh-Plesset-type equation which includes the effects ...

We are studying the problem of a stationary supersonic flow of an inviscid non-heat-conducting gas in thermodynamical equilibrium onto a planar infinite wedge. It is known that theoretically this problem has two solutions: the solution with a strong shock wave (when the velocity behind the front of the shock wave is subsonic) and the solution with a weak shock wave (when, generally speaking, th...

The flow characteristics on a truncated cone with a cylinder were experimentally investigated in a Mach 5 flow with a Reynolds number 3.8 × 10, based on the cylindrical diameter. Two different truncation ratios of 0.5 and 0.7 were used. The incidence angle varied from -12 to 0 degrees with 3 degrees intervals to investigate the influence of the truncation ratio on the surface flow pattern. The ...

Experimental studies are made on the hemi – cylindrically blunted fins for Mach 2.2 to examine the effect of dimples on shock wave / boundary layer interaction. Flow field details around hemi – cylindrically blunted fin has been captured using oil flow visualization, measurements of static and total pressures and the lambda shock has been captured by shadowgraphy. Configuration indicate nonstar...

in this research, shock wave motion, shock/boundary layer interaction, and flow separation in a transonic flow over a naca0012 airfoil were investigated experimentally. thirteen kulite sensors were utilized for measurement of pressure fluctuations over the airfoil. experiments were performed for angles of attack between -4 to 4 degrees and flow mach numbers of m= 0.39 to 0.82. the kulite sensor...

BACKGROUND Greater trochanteric pain syndrome is often a manifestation of underlying gluteal tendinopathy. Extracorporeal shock wave therapy is effective in numerous types of tendinopathies. HYPOTHESIS Shock wave therapy is an effective treatment for chronic greater trochanteric pain syndrome. STUDY DESIGN Case control study; Level of evidence, 3. METHODS Thirty-three patients with chroni...

BACKGROUND The effectiveness of extracorporeal shock wave therapy in the treatment of plantar fasciitis is controversial. The objective of the present study was to test whether focused extracorporeal shock wave therapy is effective in relieving chronic heel pain diagnosed as plantar fasciitis. METHODS Two hundred and fifty subjects were enrolled in a prospective, multicenter, double-blind, ra...
