Stochastic Flowpath Analysis of Multiphase Flow in Random Porous Media
SIAM Journal on Applied Mathematics, 2000 Multiphase flow in random porous media is studied by means of a stochastic flowpath approach, which is built upon concepts of differential geometry. This approach replaces the partial differential equations of flow by a set of ordinary differential equations along the flowpaths.

Comparison of modelling approaches for liquid fluidized beds
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

Two-phase flow experimental studies in micro-models [PDF]
, 2013 The aim of this research project was to put more physics into theories of two-phase flow. The significance of including interfacial area as a separate variable in two-phase flow and transport models was investigated.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Geophysical Monograph Series, Page 305-323., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Multiphase flow in porous media using CFD [PDF]
, 2016 We present results from a new Navier-Stokes model for multiphase flow in porous media implemented in Ansys Fluent 16.2 [1]. The model includes the Darcy-Forchheimer source terms in the momentum equations and proper account for relative permeability and ...

Demulsifying agent simplified model for offshore oil wells
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This article addresses key challenges in offshore petroleum production caused by multiphase flow instabilities, such as slug flow and emulsion formation. Traditionally, severe slugging is mitigated by increasing wellhead backpressure through partial choke valve closure. In this context, a simplified dynamic model—the fast offshore wells model (
