A coupled level set and volume-of-fluid method for computing 3D and axisymmetric incompressible two-phase flows

by Mark Sussman, Elbridge Gerry Puckett - Journal of Computational Physics , 1006
"... We present a coupled level set/volume-of-fluid (CLSVOF) method for computing 3D and axisymmetric incompressible two-phase flows. This method combines some of the advantages of the volume-of-fluid method with the level set method to ob-tain a method which is generally superior to either method alone. ..."

Under consideration for publication in J. Fluid Mech. 1 Two-Dimensional and Axisymmetric Viscous Flow in Apertures

by Sadegh Dabiri, Daniel, D. Joseph , 2007
"... The flow of a planar liquid jet out of an aperture is simulated by solving the unsteady incompressible Navier-Stokes equations. A convective equation is solved for the level set to capture the interface of the liquid jet with the gaseous environment. The flows for different Reynolds numbers and Webe ..."

The results are close to viscous potential solution except inside the boundary layers. Navier-Stokes solution for the axisymmetric aperture are also presented

A fictitious domain approach to the direct numerical simulation of incompressible viscous flow past moving rigid bodies: application to particulate flow

by R. Glowinski, T. W. Pan, T. I. Hesla, Y D. D. Joseph - J. Comp. Phys
"... In this article we discuss a methodology that allows the direct numerical simula-tion of incompressible viscous fluid flow past moving rigid bodies. The simulation methods rest essentially on the combination of: (a) Lagrange-multiplier-based fictitious domain methods which allow the fluid flow compu ..."

An Adaptive-Mesh Projection Method For Viscous Incompressible Flow

by Louis H. Howell, John B. Bell - SIAM J. SCI. COMPUT , 1996
"... Many fluid flow problems of practical interest -- particularly at high Reynolds number -- are characterized by small regions of complex and rapidly-varying fluid motion surrounded by larger regions of relatively smooth flow. Efficient solution of such problems requires an adaptive mesh refinement ca ..."
