The mathematical model and method is applied to different domains (Jiang 2009 ). In theory, it is possible to determine connectivity and permeability from stochastic parameters that describe the fracture geometry. First, splitting fractures were generated in cylindrical granite samples after high-temperature exposure (25–800 °C). Laboratory evaluations of flowmeter response to flow in fractured-rock simulators are needed to improve understanding of data collected in field settings. The rock mass was divided into two aquifer units: an upper 500-ft thick unit divided into 10 equally spaced layers through which most groundwater is. In the model, the fractured porous medium is divided into two non-overlapping sub-domains. Fractures occupy a very small volume of a subsurface formation but often dominate fluid flow, solute transport and mechanical deformation behavior First, splitting fractures were generated in cylindrical granite samples after high-temperature exposure (25–800 °C). However, the water flow in fractured aquifers can be non-laminar. Citation: Zhou X, Zhang Q, Xing H, Lv J, Su H and Huang Z (2021) Numerical Study of Reactive Flow in Fractured Carbonate Rock.
