Abstract
The numerical simulation of the plane channel filling with a polymer fluid is carried out with account for a curing reaction. Mathematical formulation of the problem includes the momentum, mass, and energy conservation equations, as well as a curing kinetics equation. The rheological behavior of the medium is described by the modified Cross model, accounting for the effect of temperature and the degree of cure on viscous characteristics. The numerical solution of the problem is based on the finite volume method, the SIMPLE algorithm and the invariant method applied for the implementation of the boundary conditions specified on the free surface. Distributions of the flow characteristics are analyzed at different time instants. Three characteristic regions are revealed in the fluid flow: a fixed layer on the solid wall with a high degree of cure, a central core with almost uniform distribution of characteristics, and a transitional region between the central core and the fixed layer.
