INFLUENCE OF VARIOUS FACTORS ON THE FLOW OF A CHEMICALLY REACTIVE NON-NEWTONIAN FLUID IN A PLANE CHANNEL

A study has been made of the fl ow of a non-Newtonian polymer medium in a plane channel and of heat transfer in it with boundary conditions of the fi rst kind for small Reynolds numbers and a large Péclet number with the Ellis rheological model with a viscosity dependent on the temperature, pressure, and degree of chemical conversion of the medium. Consideration was given to the fl ow of a high-viscosity medium with chemical reactions leading to an abrupt increase in its viscosity for whose mathematical description the authors used a model that included the kinetic chemical-reaction equation and the energy equation with a dissipative term. Signifi cant infl uence of various factors on the formation and rate of growth of the solidifi ed wall layer in such fl ow has been shown. The problem has been solved numerically by the fi nite-diff erence method according to the iterative scheme
