Abstract
The propagation of strong shock and blast waves in nature usually
results in a high-temperature two-phase gas-dust flow. In order to
understand the effect of the dust on the flow field which develops
behind such strong shocks the conservation equations for a suspension
composed of an ionized monatomic gas and small dust particles were
formulated. The equations were then solved numerically. The solution
indicates that the presence of the dust has a significant effect on the
post-shock flow properties. The effect of the dust particle density,
diameter, specific heat capacity and emissivity, as well as their
concentration in the suspension, on the various kinematic and
thermodynamic properties of the suspension inside the relaxation zone
was investigated. The dependence of the thermal and kinematic relaxation
zone lengths upon these parameters were also studied and compared with
those appropriate to an argon gas under the same conditions.
