HMS (Hydrogen Mixing Studies): A Computer Program for Transient, Three-Dimensional Mixing Gases.

摘要

A numerical technique has been developed for calculating the full three-dimensional time-dependent equations of motion with multiple species transport. The method is a modified form of the Implicit Continuous-fluid Eulerian (ICE) technique to solve the governing equations for low Mach number flows where pressure waves and local variations in compression and expansion are not significant. Large density variations, due to thermal and species concentration gradients, are accounted for without the restrictions of the classical Boussinesq approximation. Example calculations of the EPRI/HEDL standard problems verify the feasibility of using this finite-difference technique for analyzing hydrogen transport and mixing within LWR containments.
