In this study, direct numerical simulation for the bubble condensation in the subcooled boiling flow was performed. The main goal was to develop the CFD modeling for the bubble condensation and to evaluate the accuracy of the VOF model with the developed CFD modeling. CFD modeling for the bubble condensation was developed by modeling the source terms in the governing equations of VOF model usin...

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...

The free surface lattice Boltzmann method (FSLBM) is a combination of the hydrodynamic lattice Boltzmann method with a volume-of-fluid (VOF) interface capturing technique for the simulation of incompressible free surface flows. Capillary effects are modeled by extracting the curvature of the interface from the VOF indicator function and imposing a pressure jump at the free boundary. However, ob...

An exploratory study of the synthesis of vanadium (oxy)fluorides (VOFs) using ionic liquids (ILs) and deep eutectic mixtures (DESs) as a solvent yielded 10 different materials. The previously reported chain type: (NH(4))(2)VF(5) (1), (NH(4))(2)VOF(4) (2), NH(4)VO(3) (3) and (H(2)NH(2)(CH(2))(2)NH(2))VF(5) (9) have been successfully produced for the first time using ILs as the reaction media. Th...

Droplet (fluid) -droplet (fluid) interaction: A numerical investigation of binary droplet collisions in a gaseous phase has been conducted as part of the coalescence modeling project. A volume of fluid (VOF) based interface capturing method, which is characterized by introducing an extra artificial compression term into the volume-fraction transport equation, is employed to capture the liquid-g...

This letter aims to clarify the definitions of the posterior arcuate fasciculus (pAF) and the vertical occipital fasciculus (VOF). These two tracts are of interest in many different fields, including the neuroscience of language (Catani, Jones, & ffytche, 2005), post-mortem dissection (Vergani, Mahmood, Morris, Mitchell, & Forkel, 2014), reading (Thiebaut de Schotten, Cohen, Amemiya, Braga, & D...

Purpose Reproducible absolute quantification of cerebral blood volume (CBV) and cerebral blood flow (CBF) by dynamic susceptibility contrast MRI (DSC-MRI) is difficult to achieve, for example, due to partial-volume effects (PVEs). Rescaling of the arterial input function (AIF) using a corrected venous output function (VOF) in DSC-MRI has been shown to improve the correlation between CBF estimat...
