Define shockstall. shockstall synonyms, shockstall pronunciation, shockstall translation, English dictionary definition of shockstall. n the loss of lift and increase of drag experienced by transonic aircraft when strong shock waves on the wings cause th
The self-ignition of an aviation kerosene surrogate by a shock wave is studied. Based on the kinetic mechanisms of fuel surrogate combustion in air, the aviation kerosene ignition is numerically simulated. The shock wave parameters are determined. The induction time dependence on the gas temperature...
The general denomination oflaser shock processing(LSP) is applied to a class of metallic materials surface treatments conceived on the basis of the application of a laser-generated intense thermomechanical wave motivating the generation and propagation of an internal shock wave, able in turn to induc...

range of the hot gas mass flow direction is about 65 mm, which can weaken the shock wave intensity to a certain extent. WhenUDC= 1 kV actuation is applied, the influence range of the hot gas mass flow direction extends to 85 mm, and the actuation has a significant control effect on ...

In order to capture the shock wave accurately, the G2 grid near the trailing edge was refined, with the maximum cell size less than 0.5%c in the streamwise direction. A maximum wall 𝑦+<1y+<1 was achieved at the boundary layer in the wall-normal direction of all grids, as required...
Typically, shock tubes use emission spectroscopy to determine the chemical composition of the gas behind the shock wave in its non-equilibrium state. Chemical species concentrations may be determined via absorption spectroscopy. The electron density may be estimated via an indirect method, such as the...
