Automata simulation of the collision of bubbles in two-phase flow

The study of topological transitions in two-phase flow is of great importance due to the vast number of technological applications in which they occur. One modern tool for understanding the underlying physics of these transitions is the automata simulation. In this work, the collision among bubbles of low and high void fraction systems is analyzed by means of a computational model that simulates the sequential movement of bubbles. The model is two-dimensional, and the bubbles are represented by disc. Discs move one at a time driven by predefined rules and iterations are represented until a mean collision probability is obtained. As a result, predictions of the collision probability are obtained from the simulations. (author). 11 refs., 3 figs
