Abstract
In the framework of the work package #3, this report presents the Computational Fluid Dynamics (CFD) Simulation of the flow and contaminant concentration field for the aft Cleansing Station of the HFX naval ships. This is a continuation of the work done by ASC in 1992/93 on the 3D model for prediction of flow patterns and concentration distribution within a three-room and the work in 1996 within a four-room Cleansing Station. The purpose of this study, based on the previously developed model, was to investigate the effect of buoyancy on the entrainment rate of contaminant for a typical door opening and closing sequence. Based on calculated transient flow and concentration fields, it wold be possible to optimize cleansing procedures. The domain for the simulation includes the last two rooms of the cleansing station and the corridor outside the cleansing station. For all aspects of calculation in this study, the TASCflow Version 2.6 computational fluid dynamics software was employed. The TASCflow code is a finite volume method which solves the three-dimensional Reynolds-averaged Navier-Stokes equations for fluid flow within complex geometries. Since the previous report provides the details of grid generation, these matters will be described rather briefly here. However, the flow simulation method and results of simulations will be presented and discussed. TRUNCATED
