You have to explain it in a way that is straight-forward, which is not hard with (non-supersonic) fluid mechanics as it is obviously human-scale and quite visual (not so much thermodynamics/combustion or vehicle dynamics!).dans79 wrote: ↑14 Feb 2022, 20:53Having actually run college level physics labs, this is very true. It was obvious to me when a concept "clicked" with students.PlatinumZealot wrote: ↑14 Feb 2022, 18:53This is the thing with engineering, it is not a book subject, because the key part is seeing how the maths, the physics play out and how different systems interact with each other.
I.e., a hot coffee cup obviously has the same jet pattern you get in the textbooks for example (albeit distorted by ambient breeze in the room). Or our friends, the ol' hairpin vortices.
Some demonstrators seem to struggle with this and make things needlessly confusing instead of as simple as possible!
