fan flow meaning in Chinese
风扇函道气流
Examples
- The computational predictions of the centrifugal fan flow indicated that the turbulence model under - predicted gas - solid two - phase flows
计算结果表明所选的湍流模型能够很好的反映离心风机气固两相流的情况。 - This thesis presents the results of computational simulations done in parallel with experimental simulations of the centrifugal fan flow field
论文介绍了国内目前在离心风机方面主动防磨和被动防磨的相关进展和最新的研究方法。 - Aiming at the study actuality of fan performance monitoring system and analysis of fan performance curve changes affected by inlet - box and the different fixed - angles of guide blades in the course of installation , a fan flow monitoring model based on rbfnn in whole flow zone was established in this thesis . in the model , the method of no throttle and fan performance curve were used as basis . and on the basis of that model , fan performance curves of 4 - 73no . 8d were approached with experimental data of different speed , different opening - angles of guide blade and different resistance of pipeline , the precision and the error law of model were studied
本文针对电站风机性能监测系统研究较少的现状，在实验的基础上分析了现场加装进气箱和由于安装造成的导流器叶片开度不一致对风机性能曲线的影响，并在此基础上采用无节流方法测量流量，以风机调节性能曲线为依据，建立了基于径向基函数( rbf )神经网络的风机流量全程监测模型；以实验室4 - 73no . 8d离心风机为研究对象，探讨了rbf神经网络差压模型在变转速、变导流器开度和变管网阻力等工况下的应用精度和误差分布规律；最后用visualc + +语言开发了风机性能在线监测系统。
