WebMar 31, 2024 · Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula. A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe— black holes. The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away.

WebAug 19, 2024 · For an array of applications of the high voltage pulse discharge technology in reservoir stimulations and to gain a deeper understanding of the fractures mechanism of deep well rock under cyclic electrohydraulic shock waves (EHSWs), the effect of confining pressure and hydrostatic pressure on the fracturing of rock under EHSWs are investigated … Shock waves are formed when a pressure front moves at supersonic speeds and pushes on the surrounding air. [9] At the region where this occurs, sound waves travelling against the flow reach a point where they cannot travel any further upstream and the pressure progressively builds in that region; a … See more 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 … 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 … 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 … 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 … See more Shock waves can be: Normal At 90° (perpendicular) to the shock medium's flow direction. Oblique At an angle to the … See more In elementary fluid mechanics utilizing ideal gases, a shock wave is treated as a discontinuity where entropy increases abruptly as 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.
