✦ Synopsis
Experimentally observed hydrodynamic flows generated by chemical waves propagating in thin solution layers of the Belousov-Zhabotinsky (BZ) reaction have been analyzed by computer simulation of a simplified time-independent model of the experimental conditions. The assumption of density differences between the bulk of the solution and the wave is SuKrcient for an explanation of most of the features arising from the hydrodynamic flow induced by chemical waves. The calculations show that proper adjustment of only one parameter describing the density distribution is necessary to reproduce the experimental observations.
