Beschreibung

This book deals mainly with multiphase turbulent reacting flow. The two-scale two-phase turbulence models (including second-order moment model and nonlinear k-epsilon model) are established for simulating dense gas-particle flow. A new turbulence enhancement model by particle wake effect is proposed on numerical results. The USM model of non-Newtonian fluid for dense two-phase turbulent flow is developed, which combines the unified second-order moment model for two-phase turbulence with the particle kinetic theory for the inter-particle collision. Gas-particle k-equation subgrid-scale (SGS) turbulence model is established which take into account the effect of gas-particle interaction.
