Accurate solution algorithms for incompressible multiphase flows

Description: A number of advances in modeling multiphase incompressible flow are described. These advances include high-order Godunov projection methods, piecewise linear interface reconstruction and tracking and the continuum surface force model. Examples are given.

A high resolution finite volume method for efficient parallel simulation of casting processes on unstructured meshes

Description: We discuss selected aspects of a new parallel three-dimensional (3-D) computational tool for the unstructured mesh simulation of Los Alamos National Laboratory (LANL) casting processes. This tool, known as {bold Telluride}, draws upon on robust, high resolution finite volume solutions of metal alloy mass, momentum, and enthalpy conservation equations to model the filling, cooling, and solidification of LANL castings. We briefly describe the current {bold Telluride} physical models and solution … more

Low-speed flow hydrodynamics

Description: This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective of this project was the inception and development of a new casting simulation tool that is founded in modern, high-order numerical algorithms, accurate physical models, and advanced computational science constructs needed to execute efficiently on parallel architectures. This project has therefore led to the development and application… more

MESA: A 3-D computer code for armor/anti-armor applications

Description: We describe a new 3-D computer code, named MESA, developed at the Los Alamos National Laboratory with DARPA/Army/Marine Corps support specifically for simulations of armor and anti-armor systems. MESA is a three-dimensional, cartesian, Eulerian code with hydrodynamics, high explosives, and material strength models. Among special features of MESA are its high-order advection algorithm, its material interface tracking scheme and the van Leer monotonic advection limiting. We will briefly illustrat… more

A new 3D computational model for shaped charge jet breakup

Description: This paper reviews prior 1D and 2D axisymmetric, analytical and computational studies, as well as empirical studies of the shaped charge jet particulation problem and discusses their associated insights and problems. It proposes a new 3D computational model of the particulation process, based upon a simplified version of the observed counter-rotating, double helical surface perturbations, found on softly recovered shaped charge jet particles, from both copper and tantalum jets. This 3D approach… more

A parallel, volume-tracking algorithm for unstructured meshes

Description: Many diverse areas of industry benefit from the use of volume of fluid methods to predict the movement of materials. Casting is a common method of part fabrication. The accurate prediction of the casting process is pivotal to industry. Mold design and casting is currently considered an art by industry. It typically involves many trial mold designs, and the rejection of defective parts is costly. Failure of cast parts, because residual stresses reduce the part`s strength, can be catastrophic. Ca… more

Volume tracking of interfaces having surface tension in two and three dimensions

Description: Solution algorithms are presented for tracking interfaces with piecewise linear (PLIC) volume-of-fluid (VOF) methods on fixed (Eulerian) two-dimensional (2-D) structured and three-dimensional (3-D) structured and unstructured grids. We review the theory of volume tracking methods, derive appropriate volume evolution equations, identify and present solutions to the basic geometric functions needed for interface reconstruction and volume fluxing, and provide detailed algorithm templates for moder… more
