Abstract
The Bray-Humayun model for phase-ordering dynamics is solved numerical ly in one and two space dimensions with conserved and nonconserved ord er parameter. The scaling properties are analyzed in detail, and we fi nd the crossover from multiscaling to standard scaling in the conserve d case. Both in the nonconserved case, and in the conserved case when standard scaling holds an exponential tail in the scaling function is found.
