Rotating speed

3.5 rpm

14 rpm

The vortex columns spin in oppoite direction between the top and the bottom.
As the effect of the rotation increases, the temperature structures become vertically uniform.

Experimental conditions

Depth of working fluid: 6cm.
Temperature difference between cold water flowing above the working fluid and warm water flowing below: 10°C.
