Abstract. In this paper, we derive a thermodynamically consistent phase-field model for flows containing three (or more) liquid components. The model is based on a Navier-Stokes (NS) and Cahn-Hilliard system (CH) which accounts for surface tension among the different components and three-phase contact lines. We develop a stable conservative, second order accurate fully implicit discretization o...

a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...

For the calculation of reactive flows in bubble columns the local interfacial area is one of the key parameters. In addition backmixing causes a residence time distribution in the gas and liquid phase, thus mixing phenomena have to be considered as well. The three-dimensional, instationary flow fields in bubble columns are numerically calculated using an Euler multi-fluid model. The resulting s...

Real-life multiphase flows exhibit a number of complex and visually appealing behaviors, involving bubbling, wetting, splashing, glugging. However, most state-of-the-art simulation techniques in graphics can only demonstrate limited range flow phenomena, due to their inability handle the real water-air density ratio large amount numerical viscosity introduced its coupling with interface. Recent...

<p style='text-indent:20px;'>We introduce a new concept of <i>dissipative varifold solution</i> to models two phase compressible viscous fluids. In contrast with the existing approach based on Young measure description, formulation is variational combining energy and momentum balance in single inequality. We show existence dissipative solutions for large class general fluids n...

The effective parameters that influence in situ cast ferroTic composites were investigated. Centrifugal casting of specimens was carried out using ceramic & metallic molds. OM, SEM and XRD techniques were used to examine the existence of flows in the specimens. Results show that the control of chemical composition, processing, cooling rate and heat treatment has &#10a promising effect on the qu...
