Shock wave types
Web7 Jun 2024 · Shock waves are one of the possible types of surfaces of discontinuity. The appearance of discontinuities very much complicates the mathematical formulation of the problem of the flow of ideal gases and fluids, because discontinuous functions cannot be solutions of the differential equations of gas dynamics (hydrodynamics). WebThere are four types of earthquake shock waves: P-waves, S-waves, Rayleigh-waves and Love-waves. Each kind of earthquake shock wave has different properties and speeds, as …

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 … 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 See more WebThis type of shockwave therapy is frequently used to treat chronic plantar fasciitis and lower back pain. In a study of 245 patients with chronic plantar fasciitis, those who received radial extracorporeal shockwave therapy experienced a 60% reduction in their heel pain. Moreover, patients who continued to receive the therapy over the course of ...
