Small convection setup
A smaller-scale convection setup that has been actively used for many years now.
- Diameter 0.2 m.
- Two heights available: 0.2 and 0.4 m.
- Cylindrical container with square jacket, to be filled with water, offers optical access for PIV/PTV.
- Heating plate made of copper.
- Top covered with a sapphire plate connected to a water circulation cooling chamber, fully transparent from above.
- Rayleigh number range: Ra = 1 x 108 - 1 x 109.
- When placed on rotating table, Ekman numbers down to Ek = 3 x 10-6.
