In chapter four , according to the analysis on the boundary theory and velocity field of main fluid zone of two - phase fluid pumps , the parameter equations of vane ' s modular curve of centrifugal pump are given , which contact the boundary " layer and eular theory of two - phase fluid pump by the fixing angel of vane as variable and leading into the velocity coefficient a . the results show that , in designing process of vane ' s modular curve of centrifugal pump , the determination of the total shape and parameters relates the flow properties of two - phase fluid and output ability of pump , or the design of the modular curve of centrifugal pump is the kernel of hydraulic design 第四章依據(jù)固液兩相流泵的邊界層理論及對(duì)主流區(qū)速度場(chǎng)的分析,給出了離心泵葉片型線的參數(shù)方程;它是以葉片安裝角為參變數(shù),以引入的速度系數(shù)k _ v作為中間因子,將兩相流泵的邊界層理論和歐拉理論聯(lián)系起來? ?它說明了這樣一個(gè)事實(shí),在離心泵葉片型線的設(shè)計(jì)過程中,它的整個(gè)形態(tài)或參數(shù)的確定都關(guān)系到兩相流體的流動(dòng)特性和泵的輸出能力,或者說,離心泵型線的設(shè)計(jì)是其水力設(shè)計(jì)的核心。
This system tests 19 parameters such as the pressure of fore and after main fluid pumps and every sub fluid pumps " , force of pedal , turn angle of steering wheel , speed of every wheels and car body , and calculates 9 correlation analyses according to the gb112676 - 1999 " automobile system structure , capability and test methods " and gb7258 - 1997 " technical regulation of automobile safety " , also it can generate data report automatically 該系統(tǒng)對(duì)汽車制動(dòng)過程中前后液壓總泵出口液壓、各制動(dòng)分泵進(jìn)口液壓、腳踏板力、方向盤轉(zhuǎn)角、各車輪轉(zhuǎn)速、車體速度等共計(jì)19個(gè)物理量進(jìn)行測(cè)試。系統(tǒng)硬件由便攜式計(jì)算機(jī)、數(shù)據(jù)采集器以及相應(yīng)傳感器組成。硬件設(shè)計(jì)中采用了模塊化設(shè)計(jì)思想,使得測(cè)試系統(tǒng)體積小、重量輕、抗振動(dòng)、安裝拆卸方便、易于維護(hù)、可以進(jìn)行隨車實(shí)測(cè)試驗(yàn)。
In chapter five , as one of the applications of boundary layer theory on two - phase fluid pump , the calculation process and example analysis in vane design are given and the stability and convergence of algorithms and programs and rules showed in calculation are required 第五章作為固液兩相流泵的邊界層理論的應(yīng)用之一,本章給出了它在葉輪設(shè)計(jì)中應(yīng)用的計(jì)算過程及實(shí)例分析。通過實(shí)例分析及數(shù)值計(jì)算,本章得出關(guān)于算法和程序的穩(wěn)定、收斂性結(jié)論以及速度系數(shù)在計(jì)算中所表現(xiàn)出的規(guī)律性。
