TWO-PHASE OXYGEN-CARBON DUST FLOW THROUGH A NORMAL SHOCK WAVE.

The propagation of a normal shock wave into a quiescent oxygen gas seeded with carbon particles is studied. Due to the elevated post-shock temperature the carbon particles ignite and burn until they disappear. For evaluating the effect of the burning carbon particles on the post-shock wave flow field, i. e. , the relaxation zone, the conservation equations for a steady one-dimensional reactive suspension flow are formulated and solved numerically. The solution was repeated for a similar inert suspension flow. Comparing the two solutions revealed that the carbon burning has a major effect on the suspension properties in the relaxation zone and on the eventually reached post-shock equilibrium state.
