液體流出角 的英文怎麼說
中文拼音 [yètǐliúchūjiǎo]
液體流出角
英文
fluid outlet angle-
Fluid noise mainly comes from out put pulsation of rate of flow, the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition. the v trough on the port plate can reduce the fluid noise. in this paper, the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12. 3 and its length was 5mm and the cross section was an equilateral triangle
流體噪聲主要來源於輸出流量脈動，造成輸出流量脈動的主要原因是閉死容積在大圓弧段壓力切換時產生的瞬時高壓迴流，在配流盤上開設v型尖槽可降低因高壓迴流而引起的流體噪聲，本文以截流作用和液體的可壓縮性為理論依據，以matlab語言為工具，對原配流盤上的v型尖槽進行了理論計算，繪制出p - t圖線，分析了它的不足，並對原有v型尖槽進行了優化設計，得出了v型尖槽的最佳幾何尺寸：配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ，槽長5mm ，槽的橫截面為等邊三角形。Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high
通過對撞針型結構、離心式結構、較高的噴水壓力、較小的噴嘴孔徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析，得到：撞針型高壓小孔徑離心式噴嘴具有較大的空氣渦與霧化角，噴出的液體流速高、液滴小、水與空氣傳熱傳質速率高，撞針型結構提高了霧化加濕效率，高壓小孔徑的特點為霧化加濕提供了較大的能量，而噴水初溫的升高會減小水的粘性力和表面張力，從而優化加濕效果。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
第四章依據固液兩相流泵的邊界層理論及對主流區速度場的分析，給出了離心泵葉片型線的參數方程；它是以葉片安裝角為參變數，以引入的速度系數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系起來? ?它說明了這樣一個事實，在離心泵葉片型線的設計過程中，它的整個形態或參數的確定都關繫到兩相流體的流動特性和泵的輸出能力，或者說，離心泵型線的設計是其水力設計的核心。According to the theory of light transmission, we derived the expression of rotation angle as a function of the dielectric constant conductivity of er fluid, and ( the angle between the electric vector of linearly polarized light and electric field ) from maxwell ' s equations and fresnel reflection, on the condition of several appropriate approximations and assumptions
