Modeling of turbulent gas-liquid bubbly flows using stochastic Lagrangian model and lattice-Boltzmann scheme
TL;DR: In this paper, the authors presented detailed, three-dimensional and time-resolved simulations of turbulent gas-liquid bubbly flows using a lattice Boltzmann (LB) scheme, where the Smagorinsky model was used to account for the effects of the sub-filter scales.

Flow and mass transfer of fully resolved bubbles in non‐Newtonian fluids
TL;DR: In this paper, high-resolution 2D numerical simulations were performed on the motion of deformable bubbles in non-Newtonian fluids and the associated mass transfer, and it was shown that the fluid elasticity plays a major role for bubble rise velocity, and therefore, mass transfer.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
