  1. Using the opened thermosiphon of 38x3 as experimental element and water as working fluid, the characteristics of dynamic low load boiling, stable severe boiling heat transfer coefficient and critical heat flux are gotten for the opened thermosiphon at the pressure of 0. 02 - 0. 1mpa and 0. 1 - 0. 8mpa respectively, which makes up the drawback that the opened thermisiphon has not yet accurate boiling heat transfer relationship formulas. by means of experimental results, an opened thermisiphon waste heat recovery boiler is designed for the high temperature gases that the positi e electrode copper refining furnace exhaust, which overcomes effectively the drawback of short life, little capacity and unable to inspect that the closed steel - water thermosion has

    本文以工程上常用的38 3的開口封底為元件,以水為工質,對開啟式管內的動低負荷沸騰、穩旺盛沸騰及沸騰特性進行系統的可視化研究,壓力為0 . 02 0 . 8mpa ,得出了38 3的開口封底管在工作壓力為0 . 02 0 . 8mpa和0 . 1 0 . 8mpa下的管內沸騰傳系數及負荷計算關聯式,彌補了開口封底管? ?這一新型傳元件尚無準確的沸騰換關聯式的缺陷。
  2. The experimental results of the flow characteristics of the mmc heat sink indicate that the critical reynolds number signifying the transition from laminar flow to turbulent flow is in advance ; under the same experimental conditions, the variation in entrance direction of the microchannel inlet and outlet has little effect on the microchannel ; the experimental values of the friction factor of the de - ionized water in a microchannel agree well with those calculated using the theoretical laminar formula ; furthermore, a comparison of the experimental results and simulation results shows that navier - stokes equation and rng - turbulence model can be used to model the laminar and turbulence flow regions in a microchannel ; meanwhile, the correlations of the flow resistance in the turbulent flow regions for the de - ionized water as the working fluids are obtained from experiments

    對歧管式單通道沉流動特性的研究結果表明,微通道內流體流由層流向紊流轉變的雷諾數提前;改變流體的進出口方向對沉總壓降造成的影響很小;摩擦系數的值與理論值較接近;數值模擬結果能夠與值較好吻合;並由給出了紊流區流動阻力的關聯式。此外,選用十二烷基硫酸鈉( sodiumdodecylsulphate , sds )以及烷基多糖苷( alkylpolyglycoside , apg )作為減阻添加劑,研究了表面活性劑添加對微通道流動特性的影響。
  3. Aim : to analyze the mechanism, thermadynamic theoretical basis, dynamic mechanism and influencing factors of thermally induced phase separation ( tips ) in order to completely grasp the factors affecting the size, distribution and form of pores, so that the adjusted range of pore can be widened and the preparation of porous membrane can be repeated and controlled. methods : considering from the structural characteristics of tissue engineered materials, the methods of preparing porous membrane using tips technique, the hermadynamic theoretical basis, dynamic mechanism and influencing factors were analyzed, the problems and investigative directions in the future were also analyzed. tips technique is a process of phase separation of polymer homogenous solution under quenching, and it is suitable for diameter and structural form of the micropore materials prepared using tips are closely correlated with the kind and dispensing proportion of polymer attrnuant, polymer concentration and polymer molecular mass, etc. conducted, including determination of polymer - solvent system phase diagram, study of form and appearance of porous membrane of different thickness, study of form and appearance of porous membrane prepared with systems of different x, which is the parameter of polymer - solvent interaction

    目的:分析致相分離成膜過程的機理、力學理論基礎、動力學機制以及影響因素,以便充分掌握影響孔度大小、分佈、形的因素,使孔度調控范圍得以拓寬,使多孔膜的制備能重復可控.方法:從組織工程材料結構特點出發,分析致相分離聚合物多孔膜的制備方法及該法成膜的力學理論基礎、動力學機制以及影響因素.並分析中存在的問題及今後的研究方向.結果:以致相分離法可制備聚合物多孔膜.致相分離法制備多孔膜是高聚物均相溶液在淬冷條件下發生相分離的過程,它適用於上共溶溫度型聚合物一稀釋劑二元體系.致相分離法成膜的過程,可以認為是旋節線機理佔主導地位.致相分離法制備的微孔材料,其孔隙率、孔徑大小、結構形與聚合物稀釋劑的種類、組成配比、聚合物濃度、聚合物分子量等因素密切相關.結論:可採用致相分離技術制備多孔膜,通過改變不同的成膜條件可獲得一系列不同孔徑尺寸和孔徑分佈的多孔膜材料.對致相分離成膜過程中聚合物-溶劑體系的相圖測定,不同厚度的多孔膜形貌研究,不同x (聚合物-溶劑相互作用參數)體系所制備的多孔膜形貌等需深人研究
