Propagation of weak discontinuities headed by wavefronts of arbitrary shape in three dimensions are studied in vibrationally relaxing gas flow. The transport equations representing the rate of change of discontinuities in the normal derivatives of the flow variables are obtained, and it is found that the nonlinearity in the governing equations does not contribute anything to the vibrationally Cited by: 6. § Shock Waves in a Perfect Gas § Oblique Shock Waves § The Thickness of Shock Waves § The Isothermal Discontinuity § Weak Discontinuities X.

The non-linearised equations of flow for a perfectly electrically conducting and thermally radiating inviscid gas are analysed using the differential approximation for a grey gas of arbitrary opacity including effects of radiative flux, pressure and energy density. The speeds of propagation of weak discontinuities are established with oblique magnetic field, together with the jump relations Cited by: Propagation of disturbances through a uniform region of a relaxing gas in a duct with spatially varying cross section is analysed using the methods of relatively undistorted waves and weakly.

Discontinuities are interruptions in the typical structure of a material. These interruptions may occur in the base metal, weld material or "heat affected" zones. Discontinuities, which do not meet the requirements of the codes or specifications used to invoke and control an inspection, are referred to as defects.
De nition of a shock I A shock is adiscontinuityseparating two di erent regimes in an otherwise continuous medium I Shocks form when the velocities exceed the signal propagation speed I In hydrodynamics, the only wave speed is the sound speed, c s I In MHD, there are di erent characteristic speeds for each of the three modes I Not all discontinuities are shocks I Example: a static ideal gas. L.D. LANDAU, E.M. LIFSHITZ, in Fluid Mechanics, §97 Riemann invariants. An arbitrary small disturbance is in general propagated along all three characteristics (C +, C –, C o) leaving a given point in the r, an arbitrary disturbance can be separated into parts each of which is propagated along only one characteristic.
