RR457 - Specification of a Mathematical Model of a Water Reactive Pool based upon REACTPOOL
REACTPOOL is a mathematical model of the spreading and vaporisation of liquid pools resulting from accidental spillages of water reactive chemicals. REACTPOOL was developed on behalf of the Health and Safety Executive by researchers at UMIST. The basis of the model is described in a series of openly published reports.
The work presented in this report concerns reviewing the published REACTPOOL reports and deriving a mathematical model as input to the specification for a new computational model.
During the course of the review a number of mainly minor omissions have been identified and noted. Areas where the modelling might be improved have also been suggested. Based upon the review findings, a new pool model has been specified. This new model is closely based upon REACTPOOL, but differs in several respects, including:
- improvement on the REACTPOOL computational approach
- use of a better founded spreading model
- simplification of the sub-models for heat transfer from the ground and net radiation.
