Based on large eddy simulation, field simulation theory was adopted to analyze dynamic characteristics of the fire in pipe shaft of high rise building.
采用火灾过程的场模拟理论,以大涡模拟为基础,分析了火灾烟气流动过程的动力学特征;为了验证大涡模拟数值方法的准确性,针对Mercier和Jaluria竖井内的实验工况进行了模拟研究,其模拟结果与试验结果吻合较好,表明大涡模拟可以较好地预测竖井内烟气流动情况;通过设定不同的火灾场景,对不同火源功率和不同几何尺寸条件下管道井内烟气的流动过程进行了数值模拟,其结果给出了不同的几何尺寸和火源功率对管道井内所形成“烟囱效应”的影响情况。
It is also starting a research program to improve the present poor rate of success for hand-dug and tubewell projects.
它也在开始一个研究项目来提高目前可怜的手挖井和管道井项目的成功率。
