Modelling of bubbly liquid metal flows
Many applications in power engineering and metallurgy involve liquid metal two-phase flows. Due to the absence of optical access there are numerous questions regarding this kind of flow. Especially the flow control by magnetic fields is not clarified in sufficient detail. Moreover, bubble coalescence and breakup phenomena demand further investigations. Numerical simulations offer a deeper insight to the nature of liquid metal flow.
Numerical simulation of rising, deformed bubbles in a narrow box: Averaged streamlines (side-view, front-view).
To capture the complex physical phenomena numerically, the modeling of liquid metal two-phase flows has to be realized to a level of detail where individual bubbles are resolved including all interactions between the bubbles and the liquid - such as bubble deformation- as well as bubble coalescence and breakup. This allows the observation of fundamental processes determining the behaviour of both a single bubble and bubble chains and swarms.
The resulting models are validated against experimental data to prove their reliability. This provides the capability of understanding and discovering liquid metal two-phase flow phenomena.
