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 of propagation
would also change depending on the strength of this flow. Fronts in vertical
tubes can change from flat to nonaxisymmetric, and then to axisymmetric
as the density gradient is increased. Imposing a Poiseuille flow or tilting the
tube changes how this sequence takes place. In this paper, we study the
combined effects of convection and forced Poiseuille flow in inclined tubes,
solving numerically the reaction-diffusion equations coupled to the Navier-
Stokes equations.
