Pattern formation near onset of a convecting fluid in an annulus

Journal Article

A computer code was developed and applied to study pattern formation near onset of the Swift-Hohenberg model in annular domains of varying aspect ratios. Several kinds of initial conditions including small-amplitude random fields and high-symmetry states of straight, radial or concentric rolls were used to explore the possible basis of attraction. As the aspect ratio becomes larger, new patterns were observed that were characterized by radially oriented grain boundaries.
