fire

Use of computers for simulation of air flows in buildings, leading to production of a mathematical model for analysing the stability of ventilation systems subjected to external forces, and for simulation of heating systems toproduce a mathematical model of heat release and water flow in radiator systems. Investigation of fire ventilation.

Describes the computer program developed for the Fire Research Station by Scientific Control Systems Ltd. to predict the movement of smoke from a fire in a building. This can be run ineither deterministic or stochastic modes.< Explains the physical model used to describe the movement of smoke through a building and outlines the computer technique used to solve the resulting equations. Presents some preliminary results obtained with the model and considers possible improvements. Discusses applications of the model.

Gives brief description of the new computer package developed by the Oscar Faber partnership for predicting the movement of smoke during a building fire. The model treats the building as a network and calculates air flow between rooms driven by stack effect and wind pressure. Four levels of complexity in the simulation are possible. Describes the results of these different types of analysis for a multi-storey building.
