文摘
- •
A new Lagrangian Particle Tracking algorithm for LES of bubble plumes is presented.
- •
Delta functions are applied for the first time to the knowledge of the authors to this kind of problem.
- •
A new mapping approach based on the use of the bubble to mesh size ratio is suggested.
- •
We successfully validate the time-averaged velocities and second-order turbulence statistics.
- •
Slip velocity, interfacial forces and confinement effect are also analysed.
