【摘要】 FDS(Fire Dynamics Simulator)作为一种高效的火灾模拟软件,在对非长方体隧道进行火灾模拟时有很大局限性。文章提出了一种用矩形方块来拟合圆弧墙或斜线墙的算法;通过编制可视化软件来自动生成FDS输入数据,解决了在FDS中对非矩形边界隧道的建模问题;最后给出了一个在FDS中对非矩形边界隧道火灾的数值模拟实例,验证了算法的可行性。更多还原

【Abstract】 As an efficient fire dynamics simulator,FDS was limited to construct the rectangular block.This paper provids a simple algorithm to fit the non-rectangular tunnel wall using rectangular blocks.The modeling of non-rectangular wall is achieved by developing a visual software to generate the input data for FDS automatically.At last a numerical simulation of the tunnel fire with non-rectangular wall in FDS is demonstrated to verify the feasibility of the algorithm.更多还原
