Density-dependent dispersion in heterogeneous porous media Part II: Comparison with nonlinear models

Landman A.; Schotting R.; Egorov A.; Demidov D. (2007)

The results of a series of high-resolution numerical experiments are used to test and compare three nonlinear models for high-concentration-gradient dispersion. Gravity stable miscible displacement is considered. The first ...
Determination of moment tensor and location of microseismic events under conditions of highly correlated noise based on the maximum likelihood method

Birialtsev E.; Demidov D.; Mokshin E. (2017)

© 2017 European Association of Geoscientists & Engineers.We examine the problem of localization of a single microseismic event and determination of its seismic moment tensor in the presence of strongly correlated noise. ...
Mathematical Modeling and Experimental Study of Erosion-Deposition Process in Deformable Porous Media

Khramchenkov E.; Khramchenkov M.; Demidov D.; Garaeva A. (2021)

Abstract: The work is dedicated to the experimental and numerical study of a coupled erosion and deposition process in deformable porous media. The mathematical model is based on the theory of flow in deformable porous ...
Modification of algebraic multigrid for effective GPGPU-based solution of nonstationary hydrodynamics problems

Demidov D.; Shevchenko D. (2012)

We present modification of algebraic multigrid algorithm for effective GPGPU-based solution of nonstationary hydrodynamics problems. The modification is easy to implement and allows us to reduce number of times when the ...
Numerical simulation and experiments on turbulent air flow around the semi-circular profile at zero angle of attack and moderate Reynolds number

Isaev S.; Baranov P.; Popov I.; Sudakov A.; Usachov A.; Guvernyuk S.; Sinyavin A.; Chulyunin A.; Mazo A.; Demidov D.; Dekterev A.; Gavrilov A.; Shebelev A. (2019)

© 2019 Elsevier Ltd Two-dimensional flow around a semi-circular profile at the zero angle of attack and at Re = 50000 on the self-oscillatory period is extensively studied by the URANS method involving the standard ...
On the interaction between gravity forces and dispersive brine fronts in micro-heterogeneous porous media

Egorov A.; Demidov D.; Schotting R. (2005)

The concepts of homogenization theory are employed to derive a macro-scale brine transport equation for micro-heterogeneous porous medium of layered structure under assumptions of validity of classical Darcy's law and ...
Thermoelectric properties of Wigner crystal in two-dimensional periodic potential

Zakharov M.Y.; Demidov D.; Shepelyansky D.L. (2020)

© 2020, EDP Sciences / Società Italiana di Fisica / Springer-Verlag GmbH Germany, part of Springer Nature. Abstract: We study numerically transport and thermoelectric properties of electrons placed in a two-dimensional ...
Transport properties of a Wigner crystal in one- and two-dimensional asymmetric periodic potentials: Wigner crystal diode

Zakharov M.; Demidov D.; Shepelyansky D. (2019)

© 2019 American Physical Society. We study the transport properties of a Wigner crystal in one- and two-dimensional asymmetric periodic potentials. We show that the Aubry transition takes place above a certain critical ...
