Two-fluid dynamics is a challenging subject, rich both in physics and in practical applications, which range from manufacturing to lubricated transport. Mechanisms unique to a flow can be exploited to enhance functionality in applications. For example, density-matching can be used to depress the effect of gravity, or of centripetal acceleration in rotating systems, making it possible to manipul...

This work is a continuation of experimental and computational studies of the internal flow field of a large-scale Danfoss atomizer presented at an earlier ILASS conference [1,2]. Fluent 6.1 is used to simulate the flow through the large-scale atomizer. The two-phase flow is modeled using three approaches: 1) a volume of fluid (VOF) method using a laminar flow assumption, 2) a VOF method using l...

the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...

This paper presents an all-Mach method for two-phase inviscid flow in the presence of surface tension. A modified version Hartens–Lax–van Leer Contact (HLLC) solver is developed and combined first time with a widely used volume-of-fluid (VoF) method: compressive interface capturing scheme arbitrary meshes (CICSAM). novel combination yields both HLLC shock as well accurate liquid–gas tracking ch...

Numerical simulations of head-on collisions of water droplets at various Weber numbers have been performed. The Navier-Stokes equations are solved by using a finite-volume formulation on a fixed grid with a two-step projection method. Free surfaces are tracked by a technique called “volume-of-fluid”(VOF). A continuum surface force(CSF) model is used to calculate the surface tension force. Both ...

A numerical model utilizing the volume of fluid (VOF) method is proposed to simulate transient shape changes deposit front, considering diffusion-limited electrodeposition process. Modeling equations are accurately handle transport phenomena in both electrolyte (fluid) and (solid). Transient evolutions field structures, including flow, concentration, electric current density, potential, compute...
