Convective flow in a differentially heated room

Contact personnel:  P.W. Cleary

In a room of initially uniform temperature, one wall is heated to a higher uniform temperature, and the other cooled by the same amount. Hot air rises along one wall, and cold air falls along the other; at low Rayleigh number (Ra) this process is symmetric. Here Ra is very high (1.5x10⁹) close to turbulence, and deviations from symmetry do occur. These pictures are shaded according to temperature (orange is hot) and show the initial stages, in which the respective plumes cross to the other sides.
