Simulation of Combustion and Fire-Induced Flows in Enclosures

Tuovinen, Heimo (1995)
Abstract
Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. CFD modeling (computational fluid dynamics) has been used in the calculation of the flow field.

The flamelet calculations were carried out using a modified version of the Cranfield SNECKS code and CFD calculations using the Fire Research Station’s JASMINE code.

The results from both flamelet and CFD calculations agree reasonably with experimental results. Generally, the deviations from laboratory measurements are less than 30%,... (More)
