- Abstract
- This report describes a numerical computer code known as UNDSAFE-I for predicting the flow, temperature and pressure fields in a simple two-dimensional rectangular enclosure due to a volumetric heat source. it accommodates wither a doorway or a window, and a variety of conditions such as location, extent and strength of the heat source as well as various thermal boundary conditions along the ceiling and the floor of the enclosure. Physical effect taken into account in this code include strong buoyancy, compressiblility, and turbulence. The code is fully documented and explained in this report in terms of input data and format as well as available output options. A complete numerical example is presented.
