Abstract

A model of turbulent heat-and mass transfer with nonlinear sources (sinks) that appear as a result of chemical reactions of the first and second orders has been developed. The conjugation condition (equality of temperatures and local fluxes) at the reactor - coolant interface was used for this purpose. A finite-difference numerical solution by the alternating direction method is obtained. The influence of the coefficients of turbulent viscosity on heat-and mass transfer is investigated. The model has been tested on the example of modeling fast polymerization processes. It has been established in practical calculations of the processes of fast polymerization that instead of the model with variable coefficients of transfer and velocities of liquid motion one can use its approximation with constant coefficients of transfer and velocities of liquid motion.
