WebJan 4, 2024 · The sphere is represented as a boundary in the model domain because we are modeling it as a rigid object using ODEs. The fluid flow in this case is laminar, in both the air and water phases, so we can use the Laminar Two-Phase Flow, Phase Field interface. (Read this blog post on how to choose a multiphase flow interface for more information.) WebThe boundary layer over the front face of a sphere or cylinder is laminar at lower Reynolds numbers, and turbulent at higher Reynolds numbers. When it is laminar (Re 10^5), separation starts almost as soon as the pressure gradient becomes adverse (very near the shoulder, figure 3D), and a large wake forms. When it is turbulent (Re > 10^6 ...
