The modified finite volume method for simulate fluid flows
The solution of the problem of numerical simulation of the formation of fluid flows under pressure in a medium with variable porosity is considered. The data obtained in the process of m-CT tomography of real rock samples were used as a source for building a digital model of solid rock. For the numerical solution of the Navier-Stokes equations when simulating the behavior of a liquid, a modified finite volume method was used, in the implementation of which, taking into account the change in the permeability of the computational field medium was added. To conduct a numerical experiment, a software package was built that allows you to select various input data of the simulation environment, parameters of the injected fluid and visualize the results. The described approach allows multiple non-destructive studies of rock samples with different initial conditions. The main modifications of the difference scheme of the finite volume method are described to take into account the changing permeability of the medium. The results of numerical simulation are presented.
