Measurement of Convection Velocities in "Mosaic" Patterns

Article abstract of DOI:10.1021/j100344a010

Experimental evidence is given of the occurence of convection in a liquid layer of an oscillatory BZ reagent, sandwiched between two glass plates.Quantitative data on the hydrodynamic velocities are reported for three different layer depths.It is shown that convective motions result from inhomogeneities spontaneously occuring in the chemical reaction.
