Coupled turbulent heat and mass transfer in fast polymerization processes in a tubular reactor

A model of turbulent heat and mass transfer with nonlinear sources for the modeling of fast polymerization processes under matching conditions (equality of the values of temperatures and local flows) on the reactor-coolant interface was developed. The finite-difference numerical solution was obtained via the method of alternating directions. The influence of the turbulent viscosity coefficients on the polymerization process was investigated. It was shown that the separate entrance of the catalyst and monomer into the reactor leads to their mixing both during transient and steady-state modes. It was determined that the polymerization process during catalyst and monomer joint entry occurs practically by the ideal displacement mechanism.
