Laminar Flow

[GARY C]

A little different test on Laminar Flow and an awesome smoke trace flow machine at 4 minutes on this girls first science project.

Very interesting. Thanks for posting Gary.

I didn't click it yet but if that's the "Smarter Every Day" channel, he has a few videos on laminar flow, I think, and a bunch of other really interesting stuff. Laminar flow is his favorite thing in the entire world lol. He talks about it a lot. There's one vid where he shoots colored vortex rings at each other underwater thats pretty badass. IIRC, they combine and break up into smaller vortex rings.




2nd vid is 12 hr edit of what all it took for them to get this thing to work.

Here's 2 other laminar flow vids from him. He unmixes colors in these. Never seen anything like it.

In actual engines, we rarely if ever, see laminar flow.

Almost all air flow is turbulent flow.

Almost all air flow is turbulent flow.

every cycle there is a brief period where the airflow is slow or stationary so flow would be laminar

probably more applies to oil galleries or coolant channels, the latter of which is probably still fast enough to be turbulent

Yes my thought was that the more you understand the cause and effect of both then the easier you can address them and is the reason NASA and others make miniature prototypes for real world testing as was discussed in the video.

For me as a visual learner seeing simple things like this give me a better understanding of whats going on and if the idea is to make airflow less turbulent then more understanding can't be all bad.

Yeah I like his content.

This reminds me of one of my labs at NASA in the 60s. Laminar flow is fun to play around with but the majority of real life gas dynamics involve higher energy states.
