Convection In Chemical Waves, D. A. Vasquez, J. M. Littley, J. W. Wilder, Boyd F. Edwards

All Physics Faculty Publications

We present a theory for the vertical propagation of chemical waves near the onset of convection. Fluid motion, coupled to a standard reaction-diffusion mechanism for chemical wave propagation, determines the speed and shape of the reaction front in a two-dimensional slab. Our model is compared with experiments in capillary tubes. For tilted and horizontal tubes, fluid motion is always present with a corresponding increase in front speed.
