چکیده

This work is devoted to the development of a new hybrid VOF-IBM method for simulation freezing liquid films and drops. The VOF IBM methods are coupled with temperature equation be able solve icing front, dilatation induced by density difference between ice as well drop deformation balance surface tension gravity. numerical simulations validated comparison theoretical solutions experimental observations. We investigate effect Stefan number ratio solid on height evolution front both also study whole processes drops different contact angles. Furthermore, gravity investigated. distribution, solidification shape, within systematically analyzed CSF-VOF spurious currents shown induce no process due small value corresponding Weber Capillary numbers. find that final shape in very good agreement experiments, particular tip angle iced front-to-interface reproduced.

Freezing of a liquid marble.

In this study, we present for the first time the observations of a freezing liquid marble. In the experiment, liquid marbles are gently placed on the cold side of a thermo-electric cooler (TEC), and the morphological changes are recorded and characterized thereafter. These liquid marbles are noticed to undergo a shape transition from a spherical to a flying-saucer-shaped morphology. The freezin...

Freezing of simple liquid metals

Freezing of simple liquid metals and the relative stabilities of competing crystalline solids are investigated using thermodynamic perturbation theory, the interactions between ions being modeled by e€ective pair potentials derived from pseudopotential theory. The ionic free energy of the solid phase is calculated, to ®rst order in the perturbation potential, using classical density-functional ...

On the Thermodynamics of Laughlin Liquid Freezing

The competition between liquid and solid states of strongly correlated electron systems occurs in a novel way in a strong magnetic field. The fact that certain Landau level filling factors are especially favorable for the formation of strongly correlated liquid states, gives rise to the fractional quantum Hall effect. In this article we discuss some consequences of the existence of incompressib...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
