Shock wave propagation
In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in … See more Shock waves can be: Normal At 90° (perpendicular) to the shock medium's flow direction. Oblique At an angle to the direction of flow. Bow Occurs upstream of the front (bow) of a blunt object when the … See more The abruptness of change in the features of the medium, that characterize shock waves, can be viewed as a phase transition: the pressure-time diagram of a supersonic object propagating shows how the transition induced by a shock wave is analogous to a … See more Oblique shocks When analyzing shock waves in a flow field, which are still attached to the body, the shock wave … See more A shock wave may be described as the furthest point upstream of a moving object which "knows" about the approach of the object. In this description, the shock wave position is defined as the boundary between the zone having no information about the shock … See more In elementary fluid mechanics utilizing ideal gases, a shock wave is treated as a discontinuity where entropy increases abruptly as the shock passes. Since no fluid flow is discontinuous, a control volume is established around the shock wave, with the … See more Shock waves can form due to steepening of ordinary waves. The best-known example of this phenomenon is ocean waves that form breakers on the shore. In shallow water, the speed of surface waves is dependent on the depth of the water. An incoming ocean … See more Below are a number of examples of shock waves, broadly grouped with similar shock phenomena: Moving shock • Usually consists of a shock wave propagating into a stationary medium • In this case, the gas … See more Web30 Jul 2024 · For spherical explosives, the shock wave propagation characteristics are consistent in all directions due to its symmetry. However, for the cylindrical explosive, the shock wave radiates from both ends and sides of the cylinder and reflects off each other, which makes the pressure histories exhibit multiple shocks [5, 6].Moreover, the cylindrical …

Like an ordinary wave, it carries energy and can propagate through a medium (solid, liquid, gas or plasma) or in some cases in the absence of a material medium, through a field such as the electromagnetic field.
Web18 May 2024 · The FF orientations are strongly confined to a radially outward trend (WNW) relative to the crater center, which emphasizes a link between FF formation and the direction of shock-wave propagation. Thus, FFs represent an excellent tool as a stress-orientation indicator for the shock wave. Web10 Apr 2024 · The analysis of propagating an initially harmonic acoustic pulse in a semi-infinite hyperelastic rod obeying the Yeoh strain energy potential reveals attenuation with distance of the wave amplitudes caused by the elastic energy dissipation due to forming and propagation of the shock wave fronts and heat production.

Both high-resolution single shot and low-resolution video were used in a schlieren arrangement. WebThe process of shock wave propagation was visualized by the shadowgraph method and recorded by an ultra-high-speed camera. The pressure history near the interface was measured simultaneously by a needle hydrophone with high spatiotemporal resolution.
