Thermocapillary Convection in Liquid Droplets
Ғылым және технология
The purpose of this video is to understand the effects of surface tension on fluid convection. The fluid system chosen is the liquid sessile droplet to show the importance in single crystal growth, the spray drying and cooling of metal, and the advance droplet radiators of the space stations radiators. A cross sectional representation of a hemispherical liquid droplet under ideal conditions is used to show internal fluid motion. A direct simulation of buoyancy-dominant convection and surface tension-dominant convection is graphically displayed. The clear differences between two mechanisms of fluid transport, thermocapillary convection, and bouncy dominant convection is illustrated. Released Jan. 1986.

Nice and clear, old-schooled video but the content is still refreshing
Very interesting. I came here after seeing cells form in my Chammomille tea and learning that it was Reliegh Bernard convection cells. Now I'm interested enough to start experimenting and learning more about it.....
Very good video, Currently researching problems of welding in-space at my college and this effect is very intriguing regards to weld-Pool behavior during welding.

Wait, I've never thought of that! Why does my weld pool pools? There's no water/hydrogen bonds, so why is there surface tension in liquid metal?
I dig it, thanks for sharing.
Nice video
great
so cooooool
1986年已经研究到这个水平了
