Abstract
With the aim of performing large-scale simulations of dispersed two-phase flows, we show the need to include source terms in the momentum equations of the continuous phase in order to reproduce the fluid motions induced by the presence and the displacement of bubbles or particles. We study the influence of these terms on the flow generated by a single bubble in a stagnant liquid. Then we simulate a low-void fraction flow in a liquid initially at rest and we show that cellular structures with properties close to those of buoyancy-driven flows are created.
