Web1 Feb 2011 · For each distance from explosion origin we can use this formula to get overpressure (dP) and duration of positive (compression) phase in shockwave (T+), and then use dP to calculate other parameters at this range: speed of shock wave front (Vf), speed of gas behind shock wave front (Vg) and temperature in shock wave front (Tf). WebAnswer (1 of 2): As Evan Bell pointed out, it depends on the material, the pressure it’s under, the explosive, and the density of the explosive. I’ll make an analogy. If you have a long garden hose full of water and you turn the spigot on, you immediately get water to come out the other end. Is t... target outdoor christmas decorations 2020
The formation of a blast wave by a very intense explosion …
WebSo, shock waves are actually quite common in space. Interplanetary shock waves can occur due to solar flares. ‘Bow shocks’ are formed by the interaction of the solar wind with planetary magnetospheres. Supernovae create powerful shocks, both within the star collapsing to form the explosion and also moving through the interstellar medium itself. 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 … See more Oblique shocks When analyzing shock waves in a flow field, which are still attached to the body, the shock wave which is deviating at some arbitrary angle from the flow direction is termed oblique shock. These shocks require a component … 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 … 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 … See more Below are a number of examples of shock waves, broadly grouped with similar shock phenomena: Moving shock See more Web30 Mar 2024 · Chester Market explosion eye witness tells of terrifying 'shockwave' as people run from blast An eye witness who was 'only six feet away' has described the terrifying scene as people run from blast News By Angela Ferguson 13:08, 30 MAR 2024 Video Loading The aftermath of a suspected gas explosion near Chester Market target outdoor chairs manufacturer
