It allows you to determine the required amount of gas flow to provide conditions for the formation and stability of the cavity. Experimental dependences of geometric parameters of a cavity under different cavitators on the value of gas consumption used to form a cavity at different modes of flow is obtained. The mathematical model of a very non-equilibrium thermodynamic system "Soil-energy well - heat pump" which describes the energy interaction between its parts is presented. It has been shown that for soils that have a good thermal energy, several wells can be used to obtain a given power. Their total length can be substantially less than the length of a single well of the same power. Product Description popup.authors popup.nrat_date 2020-04-02 Close
