  1. Heat transfer will worsen if structure parameters of the spring inserts are not fit. the paper think that the mechanism of heat transfer enhances of the spring inserts is the laminar flow lining is thinner because of librating of the spring inserts, accordingly the part of convection is enhanced. but the part of boil is not influenced

    通過彈簧插入物的各個參數對傳熱性能的影響分析，認為彈簧插入物對豎管降膜蒸發傳熱強化的機理主要是彈簧的振動加強了液膜的湍動，減薄了層流內層，從而強化了對流傳熱分量，但對沸騰傳熱分量沒有影響。
  2. A two - dimensional double diffusive laminar natural convection in rectangular enclosure is detailed analyzed. the results show that when the thermal and solutal buoyancies aid each other, the airflow consists of one main cellular structure and is steady, regardless of the relative strength variation between the heat and pollutant sources. there are multiple flow structures, however, according to the relative strength when the buoyancies opposing each other

    模擬結果表明雙擴散自然對流系統的空氣流動與傳熱傳質特性完全是由離散熱源與污染源浮升力之間的相互作用關系訣定的：當離散熱源與污染源浮升力協同作用時，自然對流呈比較穩定的單一流動結構；而當熱源與污染源浮升力對抗作用時，自然對流系統隨它們之間強度變化呈現出多種流動狀態。
  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。
