DELTA SHOCK WAVES AS A LIMIT OF SHOCK WAVES

Journal of Hyperbolic Differential Equations, 2007
We discus the existence of delta shock waves obtained as a limit of two shock waves. For that purpose we perturb a prototype of weakly hyperbolic 2 × 2 system (sometimes called the "generalized pressureless gas dynamics model") by an additional term (called the "generalized vanishing pressure"). The obtained perturbed system is strictly hyperbolic and

Shock waves in microchannels

Journal of Fluid Mechanics, 2013
AbstractA fully instrumented microscale shock tube, believed to be the smallest to date, has been fabricated and tested. This facility is used to study the transmission of a shock wave, produced in a large (37 mm) shock tube, into a 34 $\mathrm{\mu} \mathrm{m} $hydraulic diameter and 2 mm long microchannel. Pressure microsensors of a novel design, with

Wave-function shock waves

Physical Review A, 1992
When a Rydberg state is suddenly excited to an autoionizing Rydberg state by a short-pulse core-electron excitation, a shock wave is created in the Rydberg electron's wave function. This shock wave originates at small r, at the excited core, and propagates outward.
