Reaction fronts in inclined tubes under a Poiseuille flow

Descripción del Articulo

Reaction fronts of chemical activity propagate with velocities that depend on the angle of inclination of the container. Buoyancy forces due to changes in chemical composition across the front will affect the velocity and shape of the front. If an external Poiseuille flow is imposed, the conditions...
