- JASMINE--Analysis of Smoke Movement in Enclosures
- Abstract
- JASMINE: Qualitative Assessment [1] Production of the Model: JASMINE has been produced at the Fire Research Station (FRS), Borehamwood, U. K. The name is an acronym for 'Analysis of Smoke Movement in Enclosures'. [2] Availability of the Model: At the present time JASMINE is not available for purchase. The model is run, on a consultancy basis, at two places: The Fire Research Station and the consultancy firm CHAM (Concentration, Heat and Momentum) Ltd. of Wimbledon, London. A prospective client may ask either of these establishments to run JASMINE for a particular case. [3] State of Development and Support: JASMINE has been in a state of development for many years and continues to be developed at FRS. The current version is JASMINE Version 1.2; however, later versions are expected which would incorporate different features. This study pertains only to JASMINE Version 1.2 (hereafter abbreviated to JASMINE1.2). Later versions would need to be considered in later studies. A version of JASMINE was developed at the consultancy CHAM which they call JASMINE 2. This should not be confused with the versions being developed at FRS; more is said about this later in this report, see section 12 below. The commercial company CHAM has been involved because JASMINE employs a computer package, PHOENICS, as part of its solution procedure which was developed by CHAM. More will be said about PHOENICS and its relationship with JASMINE later. It should not be assumed that the version of JASMINE which would be run for a client at FRS would necessarily be the same as the one which would be run by CHAM. Eventually it is expected to make JASMINE available as a computer package which may be purchased and run directly by a user. [4] Overall Model Type: JASMINE is a 'field model' which, escentially, simultaneously solves nine coupled partial differential equations. In contast with the zone models considered earlier in this work, JASMINE does not assume uniformity within each of a very small number of zones (basically two). In principle it assumes a variation in the 'field variables' (temperature, gas concentrations, pressure, etc.) throughout time and space. In practice, because of the solution procedure, it assumes uniformity within each of thousands of cells into which the building of concern would have been divided. JASMINE predicts the values of a large number of field variables for each cell in the space of concern.
