Mean flow and spiral defect chaos in Rayleigh-Bénard convection

Journal Article

A procedure to construct a modified velocity field that does not have any mean flow in a convecting flow was developed. Application of the procedure showed that spiral defect chaos does not survive when the mean flow is quenched. Instead, a pattern characterized by textures of stripes with angular bends appeared. Furthermore, it was shown that the mean wave numbers of these quenched patterns approach those selected by focus-type singularities.
