Importance of unsteady force and heating to particle interaction with shock/detonation waves

摘要: Particle interaction with shock/detonation waves is a fundamental phenomenon. In many practical applications, interact very large number of particles and the scales interest are typically much larger than particle size. Therefore, fully resolving flow around all impractical. rigorous models for momentum energy exchange in important. Detonation/shock-particle strongly time-dependent, so unsteady mechanisms play important roles transfer. A model that includes contributions to force heating proposed. The used investigate between an aluminum nitromethane CJ detonation wave. results computed by present show good agreement DNS results. standard drag heat-transfer correlations ignore lead significant errors.
