Vibrational Nonequilibrium

Problems concerned with the propagation of weak planar shock waves in a nonuniform, nonequilibrium gas is theoretically investigated. The medium under consideration is a diatomic thermally perfect gas with excited vibrational energy and is initially inhomogeneous with exponential density and temperature distributions. The systematic characteristic perturbation scheme is employed to render a first-order frozen shock expression. It is shown quantitatively that combined effects of nonequilibrium, nonlinearity, and stratification govern the nature of the shock wave propagation. The uniform gas limit of present theory agrees with previously known results of shock wave propagation in a general relaxing fluid. Numerical examples illustrate the variation of frozen shock strength and speed due to different magnitudes of relaxation rates and inhomogeneity. The interesting competition phenomenon between nonequilibrium effects and nonuniform effects on shock wave propagation is examined.

Methane Explosion

Coal mine can be damaged by extremely strong methane explosion, and the importance of suppressing anti-methane explosion in coal mine production safety is self-evident. The basic assumptions are used to analyze the shock wave propagation and the strength characteristics during methane explosion. The expressions among parameters in wave-front are derived during strong and weak shock wave propagation. Meanwhile, the cylinder shock wave overpressure parameter while propagating and attenuating with distance is deduced. In a certain distance away from the source location of explosion, the overpressure are basically in inverse proportion to the square root of the distance and laneway section, and is proportional to the square root of the amount of pure methane involved in the explosion. Through comparison and analysis of theoretical calculations and numerical simulation data, the data are almost identical.
