本文以國家某重點工程的風洞改造項目為背景,研究了m7 、 8噴管設計及流場校測等問題。Abstract : optimum distances between primary nozzle exit and mixing tube inlet, static pressure recovery of the mixing flow in mixing tube 、 total pressure distributions at the exit of mixing tube 、 pumping coefficients and total pressure losses of the exhaust ejector systems with four different types of primary nozzles have been measured in the experiments
文摘:對4種主噴管組成的排氣引射系統的引射系數和總壓損失、各主噴管出口與混合管進口之間的最佳間距、混合氣流在混合管內的靜壓恢復及混合氣流在混合管出口處的總壓分佈等進行了測量和對比。Flow details of measurement indicate that the coupling of periodic separated flow ( such as low frequency swinging of separation line ) with nozzle flow may cause aft - end internal flow unsteady. recirculation flow gains more energy from the main flow, at the same time the turbulence intensity increases
通過對測量結果的分析,我們認為分離流動的周期性(如分離線的低頻擺動)與噴管流動相耦合,會造成燃燒室尾部流動的非穩態效應增強,增加了迴流區從主流中獲得的能量,也加劇了流場的湍流脈動。In the aero - optical flow field tomography measurements, all projection data of different direction must be simultaneous. and the laser nozzle flow field up - stream and down - stream strehl ratio simultaneous measurements have the synchronicity requirement. the working environment of high power laser is rigorous and complicated
在考慮了由於氣動光學流場層析測量中的多個投影方向數據的同時測量、激光器噴管流場上游和下游同時測量的同步要求,以及高能激光平臺的復雜環境多方面因素的基礎上,考慮了硬體匹配的一些問題,設計了一套高速的線陣s - h傳感器。Venturi measurement of fluid flow by means of pressure differential devices inserted in circular cross - section conduits running full - part 3 : nozzles and venturi nozzles
用插入滿載的圓截面管道中的壓差裝置測量流體流量.第3部分:噴嘴和文杜利The relationship between critical pressure ratio and solid / gas ratio is thus found to provide a reference for choosing appropriate jet pipes and conditions for their applications
實驗測定了質量流量與出口壓強的關系,定義了臨界壓強比可作為判定壅塞發生與否的依據,並找出了臨界壓強比與固氣比之間的變化規律,給出了實用噴管的選擇依據和使用條件。And utilized the compatibility of software saw the optimized products. in order to advance the precision of data processing, practical quantity of flow and turnover duration were adopt to calculate the quantity of water of tilting bucket the experiment of character of tipping bucket in the measure and control system shows that the error between the measurement and calculation, ( < = 0. 01 ) decreased sharply, and the efficiency is promoted greatly
西安理工大學碩士學位論文3 .根據噴頭特性和均勻度等要求,編制了噴頭、供水支管布置優化設計的程序,並利用軟體之間的兼容性,使優化結果可視化;測控系統中的翻斗特性實驗證明,採用實測流量一翻轉歷時來計算翻斗水量,大大降低了測量和計算誤差,誤差必Used the theory of air - dynamic and the jet - ejector principle the characteristic of jet - steam, proving the noise signal have the character of chaos by using the fractal theory. noise sound pressure on the normal condition was checked by theory formula and contrasted with the experimental data. the difference was analyzed in detail
