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.

Entrance effects can persist for great lengths, L/D = 300, and long times, in developing two phase flows. Wall shear stresses at moderate and low velocities contribute only slightiy to the pressure drop in slug flows. Bubblerise velocities in slug flow are quite sensitive to the velocity profile in the water ahead of the bubbles.

Chronologically, the first attempt to use the level set method for flows involving external physics was in the area of two-phase inviscid compressible flow. Mulder et al. [115] appended the level set equation $$ {\phi_t} + \mathop{V}\limits^{ \to } \cdot \nabla \phi = 0 $$ (15.1) to the standard equations for one-phase compressible flow ...

Matter may be divided into four phases or states: solid, liquid, gas and plasma (ionized gas). The termfluid has been used as a general name for the last three states: liquid, gas, and plasma because they may be deformed without applying any force, provided that the change of shape occurs very slowly.

Introductory Remarks In Chapter 4 the basic gas–liquid two-phase flow regimes along with flow regime maps were reviewed. The discussion of flow regimes was limited to empirical methods applicable to commonly applied pipes and rod bundles. In this chapter mechanistic two-phase flow regime models will be discussed.

Abstract The various factors contributing to the motion of the bubbles in two-phase flow are analysed. A theory is presented which shows that the velocity of the bubbles consists of a component equal to the superficial liquid velocity, a component equal to the superficial gas velocity and component due to buoyancy.

Abstract As an introduction, critical (or choked) single-phase flow is first reviewed briefly. Then, in subsequent sections two-phase flow is treated in an analogous manner. Critical two-phase flow is here only considered for a one-component flow, that is for a liquid and its vapour (for example a steam-water flow). From Chapter 5 eqn (5.

The previous chapters have discussed examples of instabilities in combustors where the fuel was gaseous. However, in most practical devices, fuel is liquid (gasoline or kerosene) and the problem becomes much more difficult. In this chapter, the specificities of two-phase flow combustion will be discussed and the construction of a numerical tool to ...
