ON PLASMA DYNAMIC ASPECTS OF DETONATION AND BURNING PROCESSES SIMULATION

摘要

The simulation of detonation and burning waves propagation based on hydrodynamic heat transfer plasma approach are presented. The considered simulation gets good enough correlation with experimental data for detonation wave velocities and shows that these velocities coincide with the maximum of ion-sonic soliton velocities which determine by a ionic compound chemical components of initial detonation medium. Proposed mathematical model describes the main physical stages of detonation wave propagation: the outstripping radiation heat of detonation medium with ionization process and ion-sonic soliton formation, which determines the detonation wave velocity. Paper presents the exact solution of two-fluid hydrodynamic plasma equations. This exact solutions give the maximum velocities of ion sonic nonlinear solitons. Special consideration has fulfilled for plasma dynamic description of traditional hydrocarbon fuel. Typical structures of initial and ending burning components are demonstrated.
