Kinetic modeling of dilute solid-liquid two-phase flows with inelastic collisions

Comparison of the hyperbolic range of two-fluid models on two-phase gas -liquid flows

In this paper, a numerical study is conducted in order to compare hyperbolic range of equations of isotherm two-fluid model governing on two-phase flow inside of pipe using conservative Shock capturing method. Differential equations of the two-fluid model are presented in two forms (i.e. form I and form II). In forms I and II, pressure correction terms are hydrodynamic and hydrostatic, respecti...

Asymptotic - Preserving schemes for kinetic – fluid modeling of disperse two - phase flows with variable fluid density ∗

We are concerned with a coupled system describing the interaction between suspended particles and a dense fluid. The particles are modeled by a kinetic equation of Vlasov-Fokker-Planck type, and the fluid is described by the incompressible Navier-Stokes system, with variable density. The systems are coupled through drag forces. High friction regimes lead to a purely hydrodynamic description of ...

Modeling and Numerical Aspects of Population Balance Equations in gas/liquid-liquid Two Phase Flows

In this paper, we present numerical techniques for one-way coupling of CFD and Population Balance Equations (PBE) based on the incompressible flow solver FeatFlow which is extended with a) Chien’s Low-Reynolds number k − ε turbulence model [4], b) breakage kernel model of Lehr et al. [34, 35], c) coalescence kernel model of Lehr et al. [34]. The presented implementation ensures a strictly conse...
