The presented video demonstrates state of the art computing methods and capabilities to study multiphase flow behaviour. We quantify the contribution of the bubbles to the liquid turbulence, and demonstrate some cases for estimating the interfacial forces acting on the bubbles (such as lift and drag force). The understanding of those parameters is important to perform large domain / system level simulation of multiphase flows.
