based on the original SOLA-VOF code (Nichols et al., ) and the RIPPLE code (Kothe et al., ) capable to compute free surface flow when the fluid domain becomes multiply connected.

Impact of water droplets on a flat, solid surface was studied using both experiments and numerical simulation. Liquid–solid contact angle was varied in experiments by adding traces of a surfactant to water. Impacting droplets were photographed and liquid–solid contact diameters and contact angles were measured from photographs. A numerical solution of the Navier–Stokes equation using a Cited by: 30 2.

Due to advection, each molecule will also move uδt in the cross-flow direction. These processes are File Size: KB.

MAC was very successful for flow solution, but rather inefficient for interfaces. Later, VOF (volume of fluid) methods have emerged in many different versions, SOLA-VOF of Hirt and Nicohols () being the most widely used. The basis of the SOLA-VOF method is . In this research work the interaction between waves and horizontal slotted submerged breakwater has been investigated using numerical -dimensional numerical model based on the SOLA-VOF (SOLution Algorithm-Volume Of Fluid) method developed for wave interaction with fixed submerged breakwater has been updated in this research to study the wave interaction with horizontal slotted.

Febru  The SOLA-VOF code developed by the T-3 (Theoretical Physics, Fluids) group at the Los Alamos National Laboratory (LANL) has been extensively modified at the Oak Ridge National Laboratory (ORNL).

The modified and improved version has been dubbed ''VOLVOF,'' to acknowledge the state of Tennessee, the Volunteer state and home of ORNL. Modifications include generalization of boundary Author: J. Park. SOLA-VOF/CSL, a variety of miscellaneous updates and corrections to the original SOLA-VOF program.

In the next section the theory for incorporating an azimuthal velocity "component into SOLA-VOF is briefly described. Then, in Section 3, a discussion is given of the numerical implementation of this theory. This influences the surface tension force, which is inserted in the Navier–Stokes momentum equation, resulting in the “intentional” turning of the rim according to the prescribed contact angle value.

Pasandideh et al. made the same adjustment for a SOLA-VOF code, so did Ganesan and Sashikumaar for a Lagrangian–Eulerian approach. Similar Cited by: JOURNAL OF COMPUTATIONAL PHYS () Volume of Fluid (VOF) Method for the Dynamics of Free Boundaries* C.

NICHOLS Los Alamos Scientific Laboratory, Los Alamos, New Mexico Received November 1, Several methods have been previously used to approximate free boundaries in finite- difference numerical by: The expansion and shape change behaviors of a single rising bubble in a reduced pressure vessel were observed.

The main results obtained are as follows: 1) The aspect ratio, h/w, of a single. Experimental studies are carried out in a two-dimensional wave flume ( m long, m wide and m deep) to investigate the performance of rectangular type submerged breakwater.

A set of experiments are carried out at 50 cm still water depth with fixed submerged breakwaters of three different heights (30 cm, 35 cm and 40 cm) for five different wave periods ( sec, sec, sec, 1. The effects of viscosity and surface tension on the nonlinear evolution of Rayleigh–Taylor instability of plane fluid layers are investigated.

Full two-dimensional incompressible Navier–Stokes equations and exact boundary equations are solved simultaneously for a precise prediction of this phenomenon.

The simulation results showed that the combination of the fractional step method and VOF method can improve the computational efficiency to some extent in numerical simulation of mold filling process.
