| Abstract | The paper presents the results of investigation of hydrodynamic processes in the systems, optimization of technological parameters and heat-carrier circulation stability conditions. The solution we obtained for distribution of pressure, flowrate and leakage of fluid in the doublet circulation system. It was solved the problem of the transient heat-mass transfer in the complex fissured-porous media with constant and periodical foundary conditions. The paper presents investigation results of filtration problems in the most general formulation, with allowance for the spatial nature and complex structure of the rock material (its inhomogeneity and anisotropy). The solution of the problem on determination and estimation of the heat-carrier leakages in the underground horizon is important significance for operation of geothermal circulation systems (GCS). Heat carrier leakages influence upon stable operation of the GCS and geological environment. We consider the leakages related to the elasticity |
