Based on the analysis of air-current flowing over a single tube and a rectangular finned tube,the accumulstion of dust and the flow resistance varying with velocity of flow were discussed. According to the result of the simulating test on dusty air-current flowing over the banks of rectangular finnedtubes,an available flow velocity range has been recommended, in which air-current has a good selfblowing effect for dust under the experimental condition....

Based on the analysis of air-current flowing over a single tube and a rectangular finned tube,the accumulstion of dust and the flow resistance varying with velocity of flow were discussed. According to the result of the simulating test on dusty air-current flowing over the banks of rectangular finnedtubes,an available flow velocity range has been recommended, in which air-current has a good selfblowing effect for dust under the experimental condition. The empirical formula for calculating theflow resisance under the experimental condition has also been suggested.

以流体绕流单管和直翅片管为分析基础,定性分析了流速变化对积灰的影响和阻力随流速变化的情况。通过模拟高含尘气流绕流直翅片管束的实验研究,提出了建议选用的流速范围,在这一流速范围中,在实验的条件下有着较好的自吹灰效应。此外,给出了在实验条件下的计算阻力降的经验公式。

Numerically calculates the wind pressure distribution on model high rise buildings of various types and sizes with air current flowing around, carries out a mathematical regression of wind pressure coefficient distribution and obtains a series of fitting formulas for calculating wind load on structures and air infiltration of buildings.

高层建筑物结构风荷载与暖通渗风量的计算都依赖于建筑物外表面上的风压分布资料与风压系数的具体数据。对不同风速作用下不同体型和尺寸的空气绕流高层建筑模型外表面上的风压进行了数值计算,利用计算结果对风压系数分布进行了数学回归,并拟合出风压系数分布公式。

Using calculating program to process collected data,the functions of today′s monitoring system can be fully played.When air quantity of measurement point is given,air quantities of all branches can be obtained by using natural air distribution program.Methane concentration of each branch in down air current of methane source can be got in accordance with principles of nodal point methane quality equilibrium and equal methane concentration in each air current flowing out of the nodal point.

通过调用计算程序,对采集到的数据进行处理,可以使目前的监测系统的功能更充分地发挥作用。当测点的风量已知后,应用自然分风程序可以求得所有分支的风量。而瓦斯源下风流各分支的瓦斯浓度,可根据节点瓦斯质量平衡和流出节点的各风流瓦斯浓度相同的原理来求得。
