화재 발생시 연기 거동에 대한 수치해석적 연구 : 아트리움 공간을 중심으로 = A Numerical Study of Smoke Movement by Fire In Atrium Space

다국어 초록 (Multilingual Abstract)

The smoke filling process for the atrium space containing a fire source is simulated using two types of deterministic fire models: Zone model and Field model. The zone model used is the CFAST(version 1.6) model developed at the Building and Fire Research Laboratories, NIST in the USA. The field model is a self-developed fire field model based on Computational Fluid Dynamics(CFD) theories. This article is focused on finding out the smoke movement and temperature distribution in atrium space which is cubic in shape. A computational procedure for predicting velocity and temperature distribution in fire-induced flow is based on the solution, in finite volume method and non-staggered grid system, of 3-dimensional equations for the conservation of mass, momentum, energy, species and so forth.
The fire model i. e. Zone model and Field model predicted similar results for the clear height and the smoke layer temperature.
