1) water pressure-flow variation
水压-流量变化
2) water discharge change
水位流量变化
3) variation in wastewater flowrates
废水流量变化
4) Variable Water Volume (VWV)
变水流量
1.
Based on the energy conservation, a mathematical model of dynamic behavior of Variable Water Volume (VWV) air conditioning system was established.
根据能量守恒,建立了一个由空调房间、表冷器和冷水系统组成的暖通空调系统特性模型;在考虑了室外气候的变化和室内人员的变动情况下,对空调系统变水流量的比例积分(PI)控制以调节房间温度进行研究,分析控制参数对房间温度控制的影响。
5) flow rate change
流量变化
1.
Used Matlab to draw the flow rate-△p curves,and analysing the data of the lowest pressure from the simulation results,we get the relations among the flow rate change, angle,opening and△p,and the lowest pressure in flow field:when reducing opening and angle,the flow rate reduce greatly;when reducing opening and angle,the lowest pressure will increase,it is difficult to cavitate.
用Matlab绘制流量-压差曲线,以及通过分析流场最低压力数据,得出了节流孔压差、角度、开度与流量变化(刚度),以及流场最低压力之间的关系:减小开度和角度,流量会大幅度减小;开度和角度越小,流场产生的最低压力越大,越不容易产生负压。
6) water flow variation
水流变化
1.
Based on the surveyed hydrological and water resources data in estuary area of the Yangtze river, the water flow variation, saline water intrusion status quo and basic law in the estuary area are analysed.
根据长江河口区水文水资源勘测资料 ,分析了长江河口区水流变化、盐水入侵的现状及其基本规律。
