This chapter is the third that presents an example application of TCAT to a porous medium flow and transport problem. Single-phase flow was modeled in Chap. 9. The analysis considered three entities: a fluid phase, w, a solid phase, s, and the interface between the phases, ws. In Chap.

A multiphase formulation for two phase flows
International Journal of Numerical Methods for Heat & Fluid Flow, 1994This paper investigates the multi‐phase behaviour of droplets injected into a nozzle at two separate wall locations. The physical features of the droplets (rate of mass, density and radius) at each injector location are identical. This system can be described by a two‐phase Eulerian—Eulerian approach that yields classical systems of equations: three ...

Abstract In the previous chapters we have been concerned with the microfluidic properties of a single liquid. In Section 5.2 we went beyond the case of a pure liquid and studied the convection-diffusion equation for solutes in a solvent.

ECT Visualization of Two Phase Flows
Volume 1, 2004Electrical capacitance tomography (ECT) has been under rapid development in recent years. However, as a relatively new technology, ECT is far from mature and its applications are rather appliance-dependent, i.e. the sensor design, calibration, and data interpretation etc., depend on the understanding of the specific situations for ECT measurement.

Flow Visualization in Two-Phase Flow
1984A photochromic flow visualization technique was described in 1966 by Popovich in his doctoral thesis and was further discussed in 1967 in a series of papers by Popovich and Hummel. This technique is essentially nonintrusive and has the potential to provide accurate velocity information with a high degree of spacial resolution.

Archimedean Instabilities in Two-Phase Flows
SIAM Review, 1975We consider several problems in which two phases of matter flow through each other. In all of these problems, the motion of the two phases is described as if each were a continuum. We shall be concerned with the development in simple flows of instabilities produced by gravity through the Archimedes force.

CHARACTERISTICS OF TURBULENT TWO-PHASE FLOW
Chemical Engineering Communications, 1987Abstract The characteristics of turbulent bubbly regime of gas and liquid flow in a horizontally oriented large pipeline have been presented. Various techniques such as hot film anemometer, Pitot tube, miniature pressure transducers and orifice meters were successfully employed to measure the two-phase flow parameters, void fraction, mixture velocity ...

ON TWO-PHASE FLOW IN FRACTURED MEDIA
Mathematical Models and Methods in Applied Sciences, 2002A model describing two-phase, incompressible, immiscible flow in fractured media is discussed. A fractured medium is regarded as a porous medium consisting of two superimposed continua, a continuous fracture system and a discontinuous system of medium-sized matrix blocks.

Analysis of Nonsteady Two-Phase Flow
The Physics of Fluids, 1964The techniques for solving problems of nonsteady, quasi-one-dimensional flows by the method of characteristics have been extended to flows of suspensions of small solid or liquid particles in a gas. The particles cannot follow the rapid velocity and temperature changes that are produced by pressure waves, and complicated relaxation processes result ...

One- and two-phase nozzle flows
18th Aerospace Sciences Meeting, 1980A time-dependent technique, in conjunction with the boundary-fitted coordinates system, is applied to solve a gas-only one-phase flow and a fully-coupled, gas-particle two-phase flow inside nozzles with small throat radii of curvature, steep wall gradients, and submerged configurations.
