含有角联分支的通风网络平衡图研究

Study on Equilibrium Diagram of Ventilation Network with Diagonal Branch

通风网络中的角联分支本身具有风流不稳定的特点。从通风网路图仅能看出角联分支风流方向的改变。通风网络平衡图在定量、直观反映通风网络的拓扑关系及各种性质方面,具有优越性。应用独立通路法画出含有角联分支的通风网络平衡图,可以直观地看出角联分支风流不稳定的变化情况,从而为研究角联分支对通风网络的影响提供更有效的方法。

The diagonal branch of ventilation network has the characteristic of instable airflow. It just can be seen the change of airflow direction in diagonal branch from ventilation network diagram. Ventilation network equilibrium diagram has superiorities in quantitative and intuitional reflecting the topology relation and various properties of ventilation network. Through drawing an equilibrium diagram with diagonal branch using independent path method, the instability of airflow in diagonal branch can be seen clearly. Equilibrium diagram of ventilation network provides a more effective method for studying the effects of diagonal branch on ventilation network.
