Conditional averaging of the equations of flow in random composite porous media
The problem of conditional averaging of the transport equations is solved for a neutral impurity in a composite medium with random porosity and impurity diffusion tensor. An unclosed system of conditionally averaged equations is constructed and closed using the globally averaged equations. The average impurity concentration fields for the individual phases of the composite medium and the phase-continuum interaction characteristics are calculated.
