The relaxation zone behind ormal shock waves in a dusty reacting diatomic gas

Research output: Contribution to journalArticlepeer-review

Abstract

Ben-Dor and Igra (1982) have considered the relaxation zone which develops behind normal shock waves in dusty, reacting monatomic gases. The conservation equations were formulated and solved for argon gas seeded with inert, solid spherical particles. Solutions were obtained for shock wave Mach numbers in the range from 10 to 17, taking into acount dust particles of various characteristics. The solution of the dusty-shock equations for air is of great interest, because almost all strong shock and blast waves occur in this medium. For the present study, the main component of air, nitrogen, was used as the gaseous phase of the suspension. This study has the objective to investigate the relaxation zone which is found behind strong, normal shock waves propagating into a dusty quiescent nitrogen gas. Attention is given to the theoretical background of the study, the numerical technique, the effect of the dust mass concentration on the suspension flow field, and the effects of the dust particle emissivity on the suspension flow field.
