In this paper, interaction between oblique shock waves and hydrocarbon fueled supersonic film cooling with combustion is numerically studied using Reynolds-averaged Navier–Stokes equations. Theoretically, the
(b) The optimal number of pulse type controllable shock waves for wells of 9NAN242-S264, 9NAN256-240, 9NAN234-S268, 9NAN234-S274, and 9NAN202-S288 are 36, 30, 30, 30, and 36, respectively. (c) Oilfield production operations were completed for 5 oil wells, with an average daily...
All extracorporeal lithotripters consist of a shock wave generator, a focusing device, a coupling medium, a treatment table, and a stone localization system [6], [7]. Energy focusing is achieved by reflectors, acoustic lenses, or spherically curved sources. Shock waves are focused to the place...
The apparatus further includes a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the calcified region adjacent the balloon. The shock wave generator includes a plurality of shock wave sources distributed within the balloon, wherein...

The unsteadiness that is associated with shock waves is either inherent, or is associated with flow phenomena which are present in other parts of the flow field. Because understanding and separating the relative effects and influences of these different unsteadiness origins are challenging tasks, origin...
(Xiang and Babinsky2019) have proposed that the modified interaction could be predicted by the crossing location of compression waves emitted from corner separations. To demonstrate this effect, blockages were added to the corners of the duct to cause exaggerated corner compressions. It was observed...
The shock waves were applied using a radial extracorporeal shock wave generator (MASTERPULS MP100, STORZ MEDICAL AG, Switzerland). The frequency applied was 10 Hz, with a pressure start- ing at 2.5 bar and gradually increasing to 4.5 bar depending on the patient_s toleranc...
In the wind tunnel, 𝑀=4M=4, 𝑃0P0 = 4 bar, a solid wedge SW generator is mounted on the upper wall. Q-DC filamentary electrical discharges were arranged on the opposite wall, so that the SW from the wedge impinged on the plasma filaments that are arranged flow-wise in either a...
The arrows indicate the cone bubble (red), the toroidal bubble (yellow), and the shock waves (blue), respectively. (b) Equivalent bubble radius, Re(t) vs. time t under different γ, which is the dimensionless standoff distance. Re(t) is normalized by the maximum equivalent bubble radius...
