Transient multiphase flow simulation for unloading of frac hit gas wells
… work seeks to develop a fully step-by-step transient multiphase flow simulation valid for unloading gas wells using nitrogen. It studies the behavior of nitrogen for unloading horizontal gas wells with gas injection in the annulus. The work investigates unloading non-Newtonian fluids such as …

Coupled geomechanics and transient multiphase flow at fracture-matrix interface in tight reservoirs.
… The governing factors that characterize multiphase fluid flow mechanisms in naturally-fractured tight reservoirs - such as wellbore stability, CO2 sequestration and improved hydrocarbon recovery - are relative permeability and capillary pressure. Although the effects of geomechanical …

Modeling transient multiphase flow and mold top surface behavior in steel continuous casting
… a system of computational models to investigate transient multiphase turbulent flow physics in the mold region and mold top surface behavior during continuous casting of steel slabs. Each model can be used independently or combined together as a comprehensive system to gain insights into the …

Analytical and numerical studies of heat and moisture transfer through porous insulation
… The problem is modeled as one-dimensional, transient, multiphase flow with variable properties. Four stages in the energy and moisture transport process are identified, and they are formulated by a system of transient intercoupled equations and several thermodynamic relations using a local …

Experimental characterisation of bubbly flow using MRI
… (MRI) towards the characterisation of bubbly flow systems. The principle goal of this study is to provide a hydrodynamic characterisation of a model bubble column using drift-flux analysis by supplying experimental closure for those parameters which are considered difficult to measure by …
