An inverse energy cascade in two-dimensional low Reynolds number bubbly flows
TL;DR: In this paper, two direct numerical simulations of several buoyant bubbles in a two-dimensional periodic domain are presented, where the average rise Reynolds number of the bubbles is close to 2 and surface tension is high, resulting in small bubble deformation.

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.
