Implicit STEALTH—A Special Version of STEALTH for Low-Speed Fluid Flow Analysis— Implicit Hydrodynamics Versions

摘要

STEALTH is a family of computer codes that solve the equations of motion for a general continuum. These codes can be used to calculate a variety of dynamic physical processes associated with nuclear reaction design and analysis as well as other physical processes in which the dynamic behavior of a continuum is involved. The versions of STEALTH described in this volume were designed for the calculation of problems involving low-speed fluid flow. They employ an implicit finite difference technique to solve the one- and two-dimensional equations of motion, written for an arbitrary coordinate system, for both incompressible and compressible fluids. The solution technique involves an iterative solution of the implicit, Lagrangian, finite difference equations followed by a separate calculation of the convection terms resulting from the use of an arbitrarily-moving coordinate system.
