Течение с пропиткой химически реагирующей жидкости при формовании композитных изделий

Abstract

The problem of the isothermal flat cavity filling by a non-Newtonian fluid with simultaneous impregnation of a porous layer is considered. The flow in a cavity is described by the non-inertial Navier-Stokes equations, in a porous layer by the Darcy law, and in the region adjacent to the boundary of the liquid - porous layer by the Brinkman equation. During the molding, the processes of gelation or solidification of the binder can take place in the liquid. Viscosity is considered dependent on the degree of chemical reaction.
