Shock Waves
Shock wave theory was first studied for gas dynamics, for which shocks appear as compression waves. A shock wave is characterized as a sharp transition, even discontinuity in the flow. In fact, shocks appear in many different physical situation and represent strong nonlinearity of the physical processes. Important progresses have been made on shock wave theory in recent years. We will survey th...
متن کاملShock Waves and Cosmology
which satisfies Einstein’s equations of general relativity with a perfect fluid source. In this model, which accounts for things on the largest length scale, the universe is approximated by a space of uniform density and pressure at each fixed time, and the expansion rate is determined by the cosmological scale factor R(t) that evolves according to the Einstein equations. Astronomical observati...
متن کاملHtpniMid tram SHOCK WAVES AND SHOCK
An experimental survey of CH absorption near the QojC?) and Qlc(7) lines of the {A2A (v=0) ♦ XZn (v=0» band was obtained at 2840°K, 0.2 atm using a remotely located cw ring dye laser source and a shock tube. Mixtures of methane and argon were shock heated to provide reproducible peak concentrations of CH, and narrow-line absorption was measured in repeated experiments with the laser set at diff...
متن کاملOblique Shock Waves and Shock Reflection ∗ †
Oblique and conical shock waves are generated as solid projectile flies supersonically, or as a planar shock wave is reflected along a ramp. We study the stability of oblique shock waves for full Euler system of equations in gas-dynamics. The stability criterion is applied to the discussion of regular shock reflection phenomena and the transition of a regular shock reflection to Mach reflection.
متن کاملDynamics of Love-Type Waves in Orthotropic Layer Under the Influence of Heterogeneity and Corrugation
The present problem deals with the propagation of Love-type surface waves in a bedded structure comprises of an inhomogeneous orthotropic layer and an elastic half-space. The upper boundary and the interface between two media are considered to be corrugated. An analytical method (separation of variables) is adapted to solve the second order PDEs, which governs the equations of motion. Equations...
