摘要
In order to research temperature distribution characteristics of bedrock fracture groundwater at Zhangzhou geothermal field, a new 3D conceptual model for bedrock fracture groundwater is established and numerically solved by Fluent software.The results show the temperature distribution is strongly controlled by the fault-fracture system and a high temperature cylinder in the northwest-southeast fault formed by convection of hot water heats top surface of bedrock and thus forms the center high temperature area.The heat flux reaches maximum of 343.02 mW/m2 and 368.72 mW/m2 respectively at center high temperature areas,and reduces towards the edge of the geothermal field.The Quaternary pore water movement reduces the maximum and local heat flux.The future research on Zhangzhou geothermal field should focus on the deep temperature measurement.
