Baroclinic Instability

Experimenting with purpose-made apparatus

/

Water tank
External diameter: 20cm
Internal diameter: 10cm
Wall material: brass
Base material: acrylic
 
Working fluid
Water
 
Visualization
The temperature distribution at the base of the water tank was made visible using liquid crystal sheet. The flow of the water was made visible using aluminium powder. The flow was filmed using a video camera.
 
Experimental Process
The water tank was placed on the rotating table and a temperature difference was created using hot and cold water. The water temperature was controled using a thermo-module on the rotating table.
