For validation, this new drag was incorporated into the two-fluid model to simulate the hydrodynamic of Geldart A particles in a bubbling fluidized bed.

The utilized

two-fluid model with adoption of the original collisional closure model by Kartushinsky and Michaelides (2004) together with the applied numerical method has been verified and validated in our previous research (Kartushinsky et al., 2009a, 2009b) by comparison of numerical results with the existing experimental data by Tsuji et al.

Two-fluid model of refrigerant two-phase flow through short tube orifice.

THEORETICAL VALUES FOR Y[Ba.sub.2][Cu.sub.3][O.sub.7] ARE BASED ON THE

TWO-FLUID MODEL.

The general nature of the electro-magnetic response of a superconductor can be understood by considering the simple

two-fluid model that was developed more than 20 years before the BCS theory[8] was proposed to explain the underlying mechanism of superconductivity in conventional low [T.sub.c] superconductors.

In addition to great interest in the development and simulation of advanced

two-fluid model, high-order accuracy schemes have also attracted great increasing attention.

For the transition law of the flow patterns, Brauner and Maron [5] first developed a

two-fluid model to characterize the transition from stratified flow to other flow patterns.

One of these phenomenological models is the

two-fluid model, in which the liquid film flowing adjacent to the wall and the gas phase flowing in the tube cross-section core comprise the two fluids.

They can be classified as

two-fluid models. PHOENICS embodies the recent generalization called the multifluid model.
