Second-order accurate volume-of-fluid algorithms for tracking material interfaces

A Second Order Accurate Method in Simulation of Underwater Explosion

In this paper, a numerical scheme is proposed for the multi-fluid compressible flows. This method is applied to the problem of underwater explosion. The proposed scheme is basically the extension of Godunov method in gas dynamic problems to the multifluid environments and is second-order accurate in space. In this method, also, the problem of artificial mixing of two different phases on Euleria...

radial amniotic fluid index as a new and accurate method for measurment of amniotic fluid volume

amniotic fluid volume (afv) is one of the important parameters in the assessment of fetal well-being. the ability of ultrasound measurements to represent the actual afv is unproven. this study was undertaken to compare correlation of conventional amniotic fluid index (afi) and radial amniotic fluid index (rafi) as a new method with actual fluid volume on phantom. as an experimental study, 10 to...

A Second-order Accurate, Linearity-preserving Volume Tracking Algorithm for Free Surface Flows on 3-d Unstructured Meshes

The design of an optimal casting process begins with a fundamental understanding of the free surface flow dynamics brought about by the discharge of molten metal into a mold cavity. For the foundries at the Los Alamos National Laboratory (LANL), this discharge is initiated by a gravity pour process which results in a turbulent and topologically complex 3-D flow as the mold cavity is filled. To ...
