  1. While slug structure is leaving from computing domain, the successive disturbance develop in downstream direction, the legs of hair - pin vortex approach the wall continuously and induce vortex structures near the wall. the evolution of this near - wall vortex structures brings the secondary transition to turbulence in the pipe flow

    隨著塞流結構流出計算域，后繼擾動向下游繼續發展，表現為發卡渦的渦腳向壁面不斷貼近，進而誘發近壁渦結構，近壁渦結構的進一步演化促使圓管流動出現二次轉捩，發展到了湍流階段。
  2. Furthermore, hair - pin vortex is closely related with high - shear layer structure and spike structure in the pipe flow

    此外，發卡渦與圓管流動中的高剪切層結構以及尖峰密切關聯。
  3. Based on these parameters, the present work studies the transition of pipe flow with the different amplitude of psb disturbance. the present work simulates the whole time - space process of the transition from laminar to turbulence and secondary transition phenomenon in pipe flow for the first time. the main structure in pipe flow transition is hair - pin vortex ; the evolution of hair - pin vortex is related with the transition of pipe flow

    在這一組參數下，本文研究了不同擾動幅值的psb擾動作用下圓管流動的轉捩過程，首次給出圓管流動從層流轉捩到湍流的時空演化全過程，發現了圓管流動的二次轉捩現象，並進一步揭示了發卡渦是圓管流動轉捩中的主要結構，流動的轉捩過程與發卡渦的演化直接相關。
  4. When the legs of hair - pin vortex move to downstream and extend in azimuth direction, they cause the formation of the vortex structure near the wall. this near - wall vortex structure develops to downstream quickly

    發卡渦的渦腳在向下游發展的同時沿周向擴展，並誘發近壁渦，該近壁渦沿流向快速擴展。
  5. When the psb amplitude is weak, a series of hair - pin vortex will be formed. the formation, diffusion, breakup of the front edge of hair - pin vortex and the break of the head of hair - pin vortex lead to the first instability and form the slug structure

    在一定幅值的psb弱擾動作用下，圓管流動中出現一系列發卡渦，發卡渦前緣處環形渦的形成、擴散和破裂以及發卡渦頭部的破碎導致了流動的第一次失穩，產生塞流結構。
