Abstract
Previous studies on chaotic mixing start from the point that mixing of a single fluid is considered. This can be a very hard problem, because of the rheology of the fluid or the geometry of the mixer. Analytical expressions for the velocity field are not available anymore and numerical techniques are required. Because of the enormous increase in computer power during the last years, these computational techniques have been successfully applied to obtain a better understanding of two and three-dimensional chaotic mixing flows.
A natural next step is to study systems with multiple fluid components. Here a computational technique is presented to study multi-component mixing in two and three-dimensional systems. Because a separate (fixed) mesh is used for the flow domain and a variable adaptive mesh for the fluid components, systems can be studied with an exponential generation of interfacial area. For different systems, like the three-dimensional cavity flow, results are present. In particular, the influence of viscosity ratio and interfacial tension on the generation of interfacial area is studied.
