The subject of two- or multiphase flow has become increasingly important in a wide variety of engineering systems for their optimum design and safe operations. It is, however, by no means limited to today’s modern industrial technology, and multiphase flow phenomena which require better understandings.

Fouling dynamics in suspension flows
The European Physical Journal E, 2002A particle suspension flowing in a channel in which fouling layers are allowed to form on the channel walls is investigated by numerical simulation. A two-dimensional phase diagram with at least four different behaviors is constructed. The fouling is modeled by attachment during collision with the deposits and by detachment caused by large enough ...

Gas Dynamics and Reacting Flows
1996Let us consider a fluid in a local thermodynamical equilibrium. Then we know from thermodynamics that the thermodynamical state of the fluid is completely determined by any two thermodynamic variables. Most often, we shall note by the same letter the corresponding mathematical functions, though they differ.

Flows of mud are often encountered in nature or industry. Here we intend to review the main characteristics of free surface mud flows. First from a rheological point of view, we are dealing with viscoplastic fluids. Their behaviour can well be represented in a wide shear rate range by a Herschel-Bulkley model.

Dynamic Multiresolution Optical Flow Computation
2008This paper introduces a new algorithm for computing multi-resolution optical flow, and compares this new hierarchical method with the traditional combination of the Lucas-Kanade method with a pyramid transform. The paper shows that the new method promises convergent optical flow computation.

Symbolic Dynamics for Smale Flows
American Journal of Mathematics, 1987The author develops a symbolic model for a certain class of flows. The model is the suspension of a subshift of finite type by a continuous function. The class of flows for which this is developd is strictly larger than the class of axiom A flows where this type of construction was carried out by Bowen. The author calls these flows Smale flows.

The purpose of this work is to review the present status of both theoretical and numerical research of multiphase flow dynamics and to make the results of that fundamental research more readily available for students and for those working with practical problems involving multiphase flow. Flows that appear in many of the common industrial processes are

There are problems for contrast imaging using LevovistTM contrast agent. In case of Doppler mode, poor resolution and large blooming area are the problems. In case of 2nd harmonic imaging and pulse inversion imaging, tissue harmonic image(THI) becomes the problem because Levovist needs high mechanical index(MI).
