Reattachment point

Boundary layer separation can occur for internal flows. It can result from such causes such as a rapidly expanding duct of pipe. Separation occurs due to an adverse pressure gradient encountered as the flow expands, causing an extended region of separated flow. The part of the flow that separates the recirculating flow and the flow through the central region of the duct is called the dividing streamline. The point where the dividing streamline attaches to the wall agai… Webb11 apr. 2024 · The second issue concerns the divertor reattachment timescales following transient changes to the upstream SOL conditions. By separately increasing the neutral beam injection power and cutting the impurity gas flow, it is shown that the partially detached scenario reattaches in ~100 ms while the strongly detached X-point radiator …
