Numerical simulation of wavy falling film flow using VOF method
Surface wave dynamics of vertical falling films under monochromatic-frequency flowrate-forcing perturbations is computed by the direct simulation of Navier–Stokes equations using the Volume of Fluid (VOF) method to track free surfaces and the Continuum Surface Force (CSF) model to account for dynamic boundary conditions at free surfaces. The numerical VOF–CSF model is completely formulated, and...
متن کاملOn enhanced non-linear free surface flow simulations with a hybrid LBM-VOF model
In this paper, we present extensions, extensive validations and applications of our previously published hybrid volume-of-fluid-based (VOF)model for the simulation of freesurface flow problems. For the solution of the flow field, the lattice Boltzmann method is used, where the free surface is represented by a VOF approach. The advection equation for the VOF fill level is discretized with a fini...
متن کاملEmissions and ambient levels of sulphur dioxide in the Rijeka Bay area.
During the eighties the city of Rijeka was one of the most polluted cities in Croatia with sulphur dioxide due to high emission of this pollutant from industrial plants. In mid-eighties, annual means of SO2 exceeded 100 micrograms/m3 in the city centre, in the Bakar Bay area varied between 70-80 micrograms/m3, while in the suburban residential area they were up to 40 micrograms/m3. In 1995 annu...
متن کاملModeling of Surfzone Bubbles Using a Multiphase VOF Model
We formulate a general multiphase model representing water-bubble mixture fluid and multi-component bubble populations. An enhanced 2-DV VOF model with a k− turbulence closure is used to model the mixture fluid phase. The bubble phase is governed by the advection-diffusion equations of the gas molar concentration and bubble intensity for groups of bubbles with different sizes. The initial bubbl...
متن کاملThe rabbit costal cartilage reconstructive surgical model.
Rib grafts in facial plastic surgery are becoming more frequently used. Small animal models, although not ideal may be used to emulate costal cartilage-based procedures. A surgical characterization of this tissue will assist future research in the selection of appropriate costal segments, based on quantitative and qualitative properties. The objective of this study is to assess the surgical ana...
