ABSTRACT
Heat transfer capability of the convective boiling mechanism in the porous media is limited by the flooding phenomenon or/and frictional coupling between the phase flows. This limitation is strongly influenced by the two-phase flow pattern establishment which depends upon a set of factors, such as the boundary conditions and pore size. In this work it is considered a situation where subcooled liquid penetrates from above in the porous layer heated from below. It is shown that Taylor type instability may initiate a non-homogeneous liquid penetration in the layer in the form of columns which are spatially separated by a scale of wavelength of faster growing instability perturbation. This effect make less critical flooding limitation in the case of relatively small pore sizes because of phase flows friction diminishing in the separated phase-flow mode.
