Single bubble rising dynamics for moderate Reynolds number using Lattice Boltzmann Method
چکیده انگلیسی

Dynamics of a single rising gas bubble is studied using a Lattice Boltzmann Method (LBM) based on the Cahn–Hilliard diffuse interface approach. The bubble rises due to gravitational force. However, deformation and velocity of the bubble depend on the balance of other forces produced by surface tension, inertia, and viscosity. Depending on the primary forces acting on the system, bubble dynamics can be classified into different regimes. These regimes are achieved computationally by systematically changing the values of Morton number (Mo) and Bond number (Bo  ) within the following ranges (1×10-5
