Consolidated Compartment Fire Model (CCFM) Computer Code Application CCFM.VENTS. Part 3. Catalog of Algorithms and Subroutines (NISTIR 4344)



Leonard Y. Cooper, Glenn P. Forney


A project was carried out at the National Institute of Standards and Technology (NIST) to study the feasibility of developing a new-generation, multi-room, compartment fire model computer code, called the Consolidated Compartment Fire Model (CCFM) computer code. The ideas was that such a code would consolidate past progress in zone-type compartment fire modeling, and allow readily for integration of future advances with the greatest possible flexibility. The project lead to the development of a prototype multi-room CCFM product called CCFM.VENTS. This is Part 3 of a four-part report which documents CCFM.VENTS. It is a catalog of all the modular algorithms and associated computer subroutines used to simulate the physical phenomena in CCFM.VENTS. Each physical algorithm entry includes a description of the phenomenon simulated, a concise presentation of the calculation procedure used, identification of all input and output parameters, and a listing of the subroutine. The catalog entries have been developed and are presented as modular, stand-alone products. The stand-alone design feature allows the catalog entries to be used both in CCFM and in any other modular, zone-type, compartment fire model computer code. The other three parts of this report are: Part 1: Physical Basis; Part 2: Software Reference Guide; and Part 4: User Reference Guide.
