Abstract

The technique of field modelling is applied to predict the indoor air movement and convective heat transfer induced by thermal sources in big enclosures. This is achieved by solving a system of partial differential equations describing the conservation of momentum, enthaply and mass. The k-e model is used to describe the turbulent effect. The equations are discretized using finite difference method and solved by the Semi-Implict-Method-for Pressure-Linked-Equations-Revised (SIMPLER) scheme. Examples taken to illustrate the capability of the model are the smoke movement pattern in an atrium fire, part of an air-conditioned atrium, the ventilation of a big cargo terminal and a fire compartment for validating the field model. The predicted results are particularly useful for critizing the performance of the mechanical system in those big spaces.
