Domain Growth in a Multivariable non Potential System
R. Gallego, M. San Miguel, Raul Toral
Abstract
We present a study of dynamical scaling and domain growth in a non potential system that models Rayleigh-Benard convection in a rotating cell. In d=1, dynamical scaling holds, but the non potential terms modify the characteristic growth law with a crossover from logarithmic to linear in time. In d=2 the non potential terms prevent coarsening for any value of the angular rotation speed.
