Nonlinear hydrodynamic phenomena in Stokes flow regime
We investigate nonlinear phenomena in dispersed two-phase systems under creeping-flow conditions. We consider nonlinear evolution of a single deformed drop and collective dynamics of arrays of hydrodynamically coupled particles. To explore physical mechanisms of system instabilities, chaotic drop evolution, and structural transitions in particle arrays we use simple models, such as small-deform...
متن کاملNumerical Investigation of Multiphase Flow in Pipelines
We present and analyze reliable numerical techniques for simulating complex flow and transport phenomena related to natural gas transportation in pipelines. Such kind of problems are of high interest in the field of petroleum and environmental engineering. Modeling and understanding natural gas flow and transformation processes during transportation is important for the sake of physical realism...
متن کاملDirect Hydrodynamic Simulation of Multiphase Flow in Porous Rock
We present various numerical studies conducted with a novel pore-scale simulation technology called Direct Hydrodynamic (DHD) Simulation that can be used to study multiphase flow at various scales ranging from individual pore-scale events to complex scenarios like capillary de-saturation and relative permeability of digitized rock samples. DHD uses a diffuse interface description for fluid-flui...
متن کاملNumerical Modeling for Multiphase Incompressible Flow with Phase Change
A general formula for the second-order projection method combined with the level set method is developed to simulate unsteady, incompressible multifluid flow with phase change. A subcell conception is introduced in a modified mass transfer model to accurately calculate the mass transfer across the interface. The third-order essentially nonoscillatory (ENO) scheme and second-order semi-implicit ...
متن کاملParallel Simulation of Multiphase/Multicomponent Flow Models
The simulation of flow in porous media is a computationally demanding task. Thermodynamical equilibrium calculations and complex, heterogeneous geological structures normally gives a multiphysics/multidomain problem to solve. Thus, efficient solution methods are needed. The research simulator Athena is a 3D, multiphase, multicomponent, porous media flow simulator. A parallel version of the simu...
