The paper studies convective heat and mass transport driven by a uniform internal energy source coupled with the solid fraction in different partial air-saturated porous domains. Each domain is bounded by the top and bottom impermeable thermally conductive surfaces. The linear stability analysis is performed and the disturbance equations are derived and numerically solved. The critical internal Darcy-Rayleigh number and wave number are found and compared for three distinct domains. The first domain is an air-porous-air one, where the heat-generating porous matrix is between the upper and lower air layers. In the second air-porous domain, the air layer overlays the porous medium. In the third porous-air domain, the air layer underlays the porous medium. The bimodal marginal stability curves and regime map with a demarcation line between the local and large-scale convective flows are obtained only for the APA and AP domains due to the division of each domain into the upper unstably stratified and lower stably stratified parts. The local convection cannot originate in the PA domain because the air layer belongs to the lower stably stratified part. A remarkable destabilizing effect of additional air layers has been revealed. For example, at the fixed solid fraction of 0.1, one achieves a 40-fold reduction of the critical Darcy-Rayleigh number in the APA domain by increasing the depth ratio from 0 to 0.5. It is by 14 times in the AP domain and is only by 3.5 times in the PA domain. The destabilizing effect enhances with increasing the solid fraction.

We study the 1D initial-boundary value problem for the pseudoparabolic equation with a nonlinear convection term and a linear absorption term. The absorption term depends on a positive integer parameter $n$ and, as $nto+infty$, converges weakly$^star$ to the expression incorporating the Dirac delta function, which models an instant absorption at the initial moment of time. We prove that the infinitesimal initial layer, associated with the Dirac delta function, is formed as $nto+infty$, and that the family of regular weak solutions of the original problem converges to the strong solution of a two-scale microscopic-macroscopic model. The main novelty of the article consists of taking into account of the effect of convection.

We consider a nonlinear system of equations that describes the propagation of finite-amplitude internal waves in a two-layer stratified shallow water under a cover in the Boussinesq approximation. Within the framework of this model, we study solitary waves taking into account the non-hydrostatic pressure distribution in one or both layers, and also consider the case of weakly nonlinear waves. In the class of traveling waves, this model is reduced to an ordinary differential equation for determining the profile of a solitary wave in a shear flow. This equation admits an analytical study. The conditions for the existence of solitary waves adjacent to a given constant flow are determined by two dimensionless parameters related to the wave speed and the velocity shear of the undisturbed flow. Examples of solitary waves are given. These examples demonstrate the effects of the velocity shear on the waveform.
