- Abstract
- This report describes a numerical computer code known as UNDSAFE-1 for predicting the flow, temperature and pressure fields in a simple two-dimensional rectangular enclosure due to a volumetric heat source. A variety of conditions such as location, extent, strength of the heat source and extended outside free boundary region as well as various thermal boundary conditions along the ceiling and the floor of the enclosure. Physical effects taken into account in this code include strong buoyancy, compressiblity, turbulence and thermal radiation. 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.
