Two-way coupling in shear layers with dilute bubble concentrations. (English) Zbl 0838.76096
The authors consider “weakly dilute” suspensions of bubbles, namely flows with bubbles that are dilute enough so that bubble-bubble interactions can be negelected, but not dilute enough to ignore cumulative effects of bubbles on the flow. The governing equations for the bubble motion are discussed, and the momentum equations for this flow are derived, by using the weakly dilute assumption in a general context. Direct numerical simulations are used to analyse the evolution of a temporally growing two-dimensional shear layer seeded with bubbles of dilute concentration under gravity.
