The results of calculations of centrifugal instability in a porous microchannel are presented. The influence of the parameters of the porous medium on the critical Dean numbers is determined. A study of heat transfer during boiling of a liquid on a vertical heated wall immersed in a porous medium has been carried out. It is shown that the intensity of heat transfer during film boiling in a porous medium is weaker than in the absence of a porous medium and decreases with a decrease in the permeability of the porous medium. The effect of the Forchheimer parameter on heat transfer during film boiling in a cellular medium is determined. A numerical model of heat transfer in a porous soil mass containing a U-like vertical heat exchanger is constructed. The dependence of the energy characteristics of the operation of a heat exchanger as an element of a heat pump on the medium filling the pores, as well as on the porosity of the soil and the size of its particles is determined.
