Abstract:
The problem of coal-particle lifting and ignition in a flow field formed by a shock wave passing along a dusty surface is considered. The particle dynamics is described on the basis of the previously developed and verified mathematical model, which takes into account the action of the Saffman forces and aerodynamic interference. Simulation of the coal-particle reaction is based on the concepts of the surrounding film theory. Calculations that reveal qualitative and quantitative features of coal-particle dynamics and ignition are performed. The combined mathematical model is verified by experimental data on trajectories and the dependence of the coal-particle ignition delay on gas temperature behind the front of the transient shock wave.
Keywords:
shock waves, mixing, dust-particle lifting.
