Review of CFD Analysis of Smoke Management Systems 烟气管理系统的CFD分析综述
计算流体力学(CFD)已被用于各种消防应用,通常需要对这些CFD分析进行审查。本文介绍的审查方法包括(1)检查相关因素,(2)与实验火灾数据进行比较,(3)进行独立计算。检查相关因素可以被认为是寻找严重错误的一种形式化方法。除此之外,本文还介绍了误差类型、CFD模型、流体流动控制方程、传热、网格和单元尺寸、火灾建模和湍流建模。由于CFD分析通常是危险分析的一部分,因此包含了有关危险分析的信息。单位:I-PCITION:研讨会论文,大西洋城,2002年
Computational fluid dynamics (CFD) has been used for a variety of fire protection applications, and review of these CFD analyses is often desired. The review approach described in this paper consists of (1) checking the relevant factors, (2) comparing with experimental fire data, and (3) performing independent calculations. Checking relevant factors can be thought of as a formalized approach to searching for serious mistakes. In addition to this approach, the paper describes types of error, CFD models, governing equations of fluid flow, heat transfer, grid and cell size, fire modeling, and turbulence modeling. Information is included about hazard analysis because CFD analyses often are part of a hazard analysis.Units: I-P
