Background (from 2 years ago): What is the tag usage of [flow]?
Based on that and its accepted answer: I now created boundary-layer including usage guidance in preparation for adding the existing flow as a synonym to it. But then I found that since asking the original question the laminar-flow x7 was created. Also separation keeps getting mistaken for flow separation (examples: 1, 2) and not its intended use of traffic separation.
How best to handle all those?
