 Causing convection in a rotating system |  | 
|   | 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 .Filming conditions
