Mathematical models and numerical codes have been developed for the study of heat transfer, hydrodynamics and flow instability in porous media. The results of analytical and numerical studies of hydrodynamics and heat transfer during forced convection in porous microchannels under boundary conditions of slippage are presented. The features of heat transfer and hydrodynamics in flat and round porous microchannels and hydrodynamic flow instability in a porous medium have been determined based on the linear theory of three-dimensional and two-dimensional perturbations. A nonlinear Lorentz instability model for Van der Waals gas in a porous medium has been developed. Critical values of Rayleigh numbers for monotonic and oscillating instability have been obtained. The method of numerical modeling has determined the characteristics of heat transfer from the surfaces of buildings depending on the ratio between their height and length. The obtained results are in satisfactory agreement with the known experimental results. A numerical model of hydrodynamics and heat transfer of basalt melt in the feeder of a melting furnace has been constructed, which takes into account the dependence of its thermophysical properties on temperature. Based on the results of numerical modeling of heat transfer from a building to the ground massif through its foundation, the levels of heat loss of buildings in the presence of basements have been determined. The characteristics of the air-temperature regime of basements in the summer and winter periods of the year have been found. By numerical modeling of air flow and heat transfer in a system of annular channels, the characteristics of a heat exchanger - a recuperator of the "pipe in a pipe" type, designed to heat ventilation air.
