The Calculation Of Equivalent Thermal Conductivity And The Heat Transfer Mechanism Research Of Rock Mass And Soil Under The Condition Of Fluid-solid Coupling

Due to the complex physical properties of rock and soil which pores and cracks are welldevelopment. heat capacity and structure of rock and soil structure are association, Under theinfluence of the groundwater, rock and soil thermal capacity will received a disturbance by fluidnature.By experiment in laboratory could get part of the necessary experimental data, combinedwith the numerical simulation method to analysis the thermal capacity of rock and soil. Takesome physical parameters as the information element which have affection on the thermalconductivity of rock and soil, Then proceed a series of separate analysis that contain porosity,cracks, fissures water flow rate and fluid viscosity and all of them are information element whichhave different effects on rock and soil heat transfer, obtained information element of rock andsoil temperature field impact. Anti-fluid-structure interaction analysis under the conditions of,the information element of rock and soil thermal conductivity coefficient, fitting differentinformation elements and the relationship between the equivalent thermal conductivity, andfluid-structure interaction of rock and soil under the conditions of preliminary heat transfermechanism of. Two examples cited by porosity and fluid viscosity correction of the equivalentthermal conductivity, thermal conductivity obtained for the revised engineering practice isequivalent to the impact effect...
