To model an unbounded system, we have therefore been led to conduct the present experiments in an annular convectioncell. It is possible to make a convectioncell with mean circumference of greater than 100 times the cell height. These density differences result in rising and/or falling currents, which are the key characteristics of a convectioncell.

One obvious method to suppress higher-dimensional behaviour in convection in rectangular containers is t o use narrow convection cells. The z-independent perturbation to the stream function is positive in the region near the wall where the convection cells are strongest. In this investigation an initial disturbance of the form of the counter-rotating convection cells predicted by linear theory was used. However, the linear results have counter-rotating convection cells, and experiments have only revealed cells that all rotate in the same direction. The instabilities that evolved consisted only of co-rotating convection cells. The heat is dissipated through large-scale convection cells. By its very nature the linear stability analysis predicts counter-rotating convection cells. See all examples of convection cell These examples are from corpora and from sources on the web.
