Simulation of fluid flow in the pore space of the core obtained by x-ray microtomography
Abstract
This paper considers the results of numerical simulation of fluid flow. The computational domain represented the three-dimensional pore space obtained from processing digital images of X-ray microtomography. The model of the laminar fluid flow was used in calculations and described by the continuity and Navier-Stokes equations. The numerical simulation was conducted using the FlowVision software for stationary flow and for the flow with superimposed pressure pulsations. Velocity and pressure fields were obtained as a result of calculations. It was found that superimposed oscillations lead to additional directed flow occurrence with average characteristics depending on parameters of superimposed unsteadiness.
