Parametric study of a two-phase gas-dust suspension behind strong normal shock waves

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


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.
