  1. 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

    對歧管式單通道熱沉流動特性的研究結果表明,微通道內流體流態由層流向紊流轉變的臨界雷諾數提前;改變流體的進出口方向對熱沉總壓降造成的影響很小;摩擦系數的實驗值與理論值較接近;數值模擬結果能夠與實驗值較好吻合;並由實驗給出了紊流區流動阻力的實驗關聯式。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。
  2. This experiment include many contents, in a word, that is summer condition experiment, winter condition experiment > summer - winter transition condition experiment and winter - summer transition condition experiment, furthermore summer condition experiment still include flux changing experiment and winter condition experiment still include thermal balance experiment this article dealt with the data of the test, calculating out energy absorbing ( energy discharging ) of buried pipe in winter condition ( summer condition ), input power of heat pump x heat exchanging of piece buried pipe length x co - efficiency performance ? op ( energy efficiency rate ? er ) and average heat exchanging coefficient ; in additiont this article compares the inlet water temperature and outlet water temperature of underground the first layer and the second layer buried pipe when heat pump was running, the results are that the heat exchanging ability of the second layer buried pipe outgos the first layer buried pipe, and heat exchanging is more stable ; and still analyse earth temperature resuming in the transition season. the results are earth temperature resume fast in the first week when the heat pump runs off

    本文測試內容相當多,概括地說就是四個工況的測試,即夏季製冷工況的測試、冬季供熱工況的測試、夏?冬過渡季測試和冬?夏過渡季測試;另外在夏季工況的測試中還進行了變流量測試,在冬季工況的測試中還進行了熱平衡測試。本文對測試數據進行了處理,計算出了冬(夏)季工況埋管吸(放)熱量、熱泵空調器供熱量(製冷量) 、熱泵空調器輸入功率、埋管單位管長換熱量、供熱性能系數(製冷能效比)和平均傳熱系數等;另外,還比較了熱泵運行時地下一二層埋管進出水溫度變化情形,得出地下二層埋管換熱能力優于地下一層埋管,且換熱很穩定;並分析了過渡季地下一二層埋管溫度恢復情形,得出熱泵系統停機一周內地溫恢復特別快。
  3. Scramjet combustor may realize the subsonic - combustion mode and supersonic - combustion mode respectively based on the control of fuel in variable flight conditions. isolator has great effect on mode transition and preventing unstart of inlet. inlet can be unstarted by raising the back pressure result from chemical energy release in the combustor

    計算研究表明,在相同的來流條件下,供油規律對燃燒室的工作模態有著重大的影響;在不同的來流條件下,可以通過調節供油規律使燃燒室分別實現亞燃模態和超燃模態;隔離段對防止燃燒引起的壓力升高對進氣道的干擾和燃燒室的模態轉換具有重要的作用。
  4. It means that the cheap polymers are chosen as the substrates, and a 248nm excimer laser with flexible and automatic characters is selected as a new micro - fabrication technique. the most important problem of continuous - flow pcr chip is the transition length computation of temperature or velosity distribution from inlet to steady status

    隨后針對目前國內外pcr微流控晶元的研究現狀,提出了採用準分子激光微細加工技術在價格便宜、生物兼容性好的聚甲基丙烯酸甲脂材料( pmma )上制備pcr微流控晶元的新方法。
