Some Field Model Validation Studies

The three dimensional time-dependent field model known as JASMINE has been applied to several experimental fire configurations for validation purposes. Comparisons of predictions with non-spreading experimental fires conducted in a forced ventilated fire test cell (6 m x 4 m x 4,5 m), closed six-bed hospital ward (7.3 m x 7.9 m x 2.7. m) and a railway tunnel, both forced and naturally ventilated (390 m x 5 m x 4 m) are summarised in this paper. The agreement is shown to be quite satisfactory except in the immediate vicinity of the fire source. It is suggested that the model may now be used with some caution to study smoke movement problems, however, improvements to the turbulence chemistry interaction at the source will be required before the spreading fire can be reliably predicted.
