- 摘要：
- The void fraction profile and distributing mechanism of small bubbles were investigated in detail by using the Euler–Lagrange two-way model. The continuous phase is simulated by using direct numerical simulations in Euler frame of reference. Bubble trajectories are tracked by solving the Newton equations of motion with considering forces including gravity force (buoyant force), drag force, lift force, wall lift force, pressure gradient force, virtual mass force, and inertia force in Lagrange frame of reference. Results show that the void fraction profile of small bubbles exhibits double peak values, which is caused by different interphase forces dominating over bubble movements at different bubble places, and paths of bubbles are directly related to their injection places.
