" 3-D Particle Modeling of Gas Bubbles in a Liquid " We use a molecular aggregate approach and classical molecular dynamics type formulas to simulate the motion of gas bubbles within a liquid. For application, the liquid is taken to be water while the gas is taken to be carbon dioxide. The resulting dynamical equations are large systems of second-order, nonlinear, ordinary differential equations which are solved by a time-stepping numerical method. The rise of the bubbles and the motion of the water near the bubbles are described and discussed. |
