星期三傍晚下班交通高峰時期，密西西比河上方一座年逾40的橋轟然倒塌，斷橋的鋼筋混凝土掉入水中激起很多旋渦，水下救生員在能見度只有一英尺的水中經過認真摸索找到了一些被捲入急流旋渦中的汽車的位置Based on detailed analyze on turbine engine and ramjet, a new conceptive internal - rotor burnt rotating ramjet ( irbrr ) with an rotating cylinder in the center of rotor in which the revolved stream can be ram - compressed and burnt has been proposed and some primary research have been done as below : the scheme of structure, principles, thermodynamic cycle and performances of the new conceptive engine has been studied in the paper
本文通過對燃氣渦輪發動機和航空沖壓發動機的原理結構進行詳細分析並進行融合創新，提出了一種利用內置旋轉汽缸進行旋轉氣流沖壓壓縮和旋流燃燒的新概念內置燃燒室旋轉沖壓發動機，並進行了一些前期的基礎性探索研究，具體研究內容有:對旋轉沖壓發動機進行了總體方案設計、工作原理分析、氣動熱力循環和性能分析等概念性研究。The vortex - excited oscillation, wake galloping, rain - wind vibration and buffetting are the main cause of the fatigue in the vicinity of the anchorages on cables of cable stayed bridges
渦激振、風雨振、尾流馳振、抖振等風致振動容易造成斜拉橋拉索錨固端疲勞，促使銹蝕加快，嚴重影響拉索的使用壽命。Stay cable, which is one of the important components in cable - stayed bridges, is susceptible to environmental excitation because of its small weight, large flexible, low damping, then the various vibration is induced, such as vortex - induced vibration, wake galloping, rain vibration, buffeting as well as parametric - induced vibration etc. in this paper, the vibration property of stay cable has firstly been introduced
斜拉索是斜拉橋的重要承力構件，由於拉索自身的質量輕、柔度大、阻尼小，在外界激勵下，易發生各種振動，包括渦激振、尾流馳振、風雨振、抖振以及參數振動等。Stay cables of the long - span cable - stayed bridges are susceptible to vibration under wind loading, or wind incorporated rain excitation, or deck motion due to high flexibility, relatively small mass and very low inherent damping, such as vortex shedding, wake galloping, parameter resonance and wind - rain induced vibration. large - amplitude vibration of cables may reduce the life of cables and threaten safe traffic, and has been considered today as one of the most critical problems for this type of bridge
大跨度斜拉橋拉索具有較小的質量和極低的阻尼，在風、風雨及橋面振動等外部激勵下極易發生振動，如渦激共振、尾流馳振、參數共振和風雨振等，拉索的大幅振動對拉索的使用壽命和橋梁安全運營構成極大威脅，它已成為大跨度斜拉橋急需解決的關鍵問題之一。To investigate the aerodynamic design ideas and concrete methods of high performance low pressure turbine ( lpt ) at low reynolds number condition, a new lpt of high load, large chord and proper velocity distribution was designed
摘要為了探索高空低雷諾數情況下高性能低壓渦輪部件的氣動設計思路和設計方法，通過採用高負荷、大弦長的葉片設計和選擇恰當的葉片表面速度分佈形式設計了一臺新低壓渦輪。A " saddle " shape appears in the curve of relationship between smd ( sauter mean diameter ) and charging voltage, the droplets " size distribution fluctuates with the change of charging voltage. the influence of electric field on flow field is apparent. the distribution of velocity and turbulent energy, structure and size of vortex appear different changes with the increase of voltage of charging
索太爾粒徑隨電壓的變化曲線中出現「馬鞍」現象，粒徑的分佈情況隨電壓的升高出現波動性變化；電場對流場的作用明顯，速度與湍能的分佈及渦的結構等流場特性隨電場的改變均有不同規律的變化。The company, after many years of exploration, research, for the existing market demand and successfully developed : twdj series turbine mill, the tcm series vortex flow ultrafine grinding mill plastic tfsm series, tcwm series super swirl polishing, tldj series screen shaft extruder - mill equipment, and other varieties of sets of mechanical equipment
