Modeling investigation of the impacts of dead-end fracture on heat transfer of water flowing through rough fractured rocks

A clear understanding of the convective heat transfer characteristics of fluid in three-dimensional (3D) rock fractures affected by dead-end fractures is important in evaluating heat recovery in fractured geothermal reservoirs. Two 3D cubic fractured rock models with and without rough dead-end fractures are built to conduct flow and heat transfer simulations by solving hydrothermal coupling equations. The rough fractures are upscaled from...
