热-流-固耦合条件下的三维粗糙单裂隙岩体渗流传热研究
Research on seepage and heat transfer of three-dimensional rough single-fractured rock mass under thermal-fluid-solid coupling conditions
摘要
Abstract
In order to study the coupling effect between seepage,stress and heat transfer in rough fractured rock mass under confining pressure,considering the influence of matrix permeability on heat transfer in rough fractured rock mass,a three-dimensional thermal-fluid-solid coupling model of rough fractured rock mass was established by COMSOL software.The results show that ignoring the permeability of the fractured matrix will underestimate the heat transfer capacity of the fractured rock mass,and the higher the matrix permeability,the better the heat extraction effect.The fracture roughness and confining pressure have a great influence on the heat transfer of the fracture,and the larger the roughness J RC,the higher the outlet temperature,and the greater the confining pressure.关键词
