Which bring up a conclusion that the zoon model is not agree with the facts of fire experiment , hence the field model or the combined model is better for the simulation of fires in a large volume building 本文结合火灾相似模型实验研究,对中庭建筑火灾过程进行了数值模拟研究,建立了火区燃烧及蔓延过程与烟气流动过程相互耦合的气-固两相火灾模型。
As a rule , in the system of construction , it is very difficult to apply the experimentation to obtain the data . so , the technology of computer simulation becomes the strong instrument to solve these questions 而在一些工程施工系统中,又不可能采用模型实验的方法得到为施工方案决策的有用数据,此时,利用计算机模拟技术就为解决这些问题提供了有力的手段。
The physical and chemical processes of nozzle atomization and the evaporation , mixing and combustion of propellant drop flow are very complex . for the reason , the researches on nozzle are still based on the experimental research now in or abroad 由于喷嘴雾化及其喷雾流的蒸发、混和和燃烧是一个非常复杂的物理化学过程,目前国内外对喷嘴的研究仍以模型实验研究为主。
The experiment model that scale is 1 to 2 . 5 was made . model experiment results show that numerical simulation scheme has gratifying precision and is very effective for forecast of resistance characteristics of marine exhaust mufflers 按照所确定的结构制作了几何比为1 : 2 . 5的实验模型,模型实验结果表明,本文的数值模拟方案具有令人满意的精度,对于船用排气消声器阻力特性预估是非常有效的。
This paper also does some primary research for model experiment if this prediction way , model experiment and fact measure can be fell together , then some factors which is difficult to consider will be corrected , by this way the result will be more precise 本文还对声学模型实验进行了一些初步的探索,若能将本文的预测方法与模型实验和实测结合起来,对一些难以考虑的因素进行修正,必将得到更加准确的结果。
The results of the research was succeeded in applying to the experiments of the fast 50 meters model in the xidain university and thsinghua university . moreover , which also provided a feasible and available project for surveying the kinetic feed hi fast 500 meters pro totype 研究成果在西安电子科技大学和清华大学fast50米缩比模型实验中得以成功应用,为fast馈源动态测量提供一种有效可行的测量技术方案。
It needs more manpower and material resources as well as longer experimental period to realize characteristic of the different inertial stages and multilayer gauze stages absolutely by model experimentation , so numerical simulation studying method has important meaning 完全通过模型实验来了解不同惯性级和网垫级的特性既耗费较大的人力物力也需要较长的实验周期,因此,用数值模拟方法进行研究具有重要意义。
