Calculation of unsteady flow for interaction between rotating impeller and vaned diffuser 旋轉(zhuǎn)葉輪和葉片擴(kuò)壓器耦合的非定常流動(dòng)計(jì)算
The results also display the impeller ' s good hydraulic properties and the vaned diffuser ' s imperfect hydraulic properties and low efficiency 計(jì)算結(jié)果還顯示:潛油泵葉輪有較好的水力性能,而潛油泵導(dǎo)輪的水力性能是不完善的,效率較低。
The internal flow field in submersible centrifugal pump is researched based on cfd , and numeric results of the impeller and vaned diffuser trader three different operating conditions are discussed and analysed 摘要采用cfd方法研究了潛油離心泵的內(nèi)部流場(chǎng),討論分析了3種不同工況下葉輪和導(dǎo)輪的數(shù)值計(jì)算結(jié)果。
