NONISOTHERMAL FLOW OF A REACTIVE FLUID WITH SIMULTANEOUS IMPREGNATION OF A POROUS LAYER

Consideration is given to the nonisothermal filling of a plane cavity with a Newtonian chemically reactive fluid with simultaneous impregnation of a porous layer. Flow in the plane cavity is described by noninertial Navier–Stokes equations, and in the porous layer, by the Darcy equation; fl ow in the region adjacent to the boundary between the fluid and the porous layer is defi ned using the Brinkman equation. The viscosity is taken to be dependent on temperature and on the extent to which the chemical reaction proceeds. A single-temperature model is used as the energy equation. Temperature fi elds in the region of a channel and in the porous layer are interrelated by conjugate fourth-kind boundary conditions. An example of determining the maximum allowable molding time is shown.
