在此基礎上模擬在冬夏兩季不同情況下，不同流速對熱管空氣預熱器壁面溫度的影響；然後對影響整個流場分佈的各種因素：包括分流板長度、厚度、偏離中心流道位置的偏離度、飛灰濃度、飛灰粒徑等因素進行數值模擬；最後提出在分流煙道轉彎處加裝導流板，並模擬加裝導流板后的流場分佈，得到下級空氣預熱器出口、熱管空氣預熱器進口處的斷面速度場分佈、濃度場分佈，以論證加裝導流板能達到流場均勻化的作用。At the same time, in the field of warm extrusion forming technique for pockety wall thickness forging, the research conclusion of this paper has important leading meaning and application value
同時，本論文的研究成果對非均勻壁厚鍛件的溫擠壓成形工藝研究有重要的指導意義及實用價值。The inside fashion of the sway oil pump stator is complex, its wall thickness is pockety and the metal flow law is difficult to master. at the present time, the investigation of warm extrusion forming technique for the nonuniform wall thickness forging has few to been done. the forming technique and die configuration which use for production have not achieve optimization
由於轉向油泵定子的內部形狀復雜，零件壁厚分佈不均，金屬流動規律難于掌握，目前人們對這種非均勻壁厚鍛件的溫擠壓成形工藝研究幾乎沒有，其成形工藝及生產用模具結構並未達到最優化。In the end, the mechanism of explosive accidents of lpg vessel under high temperature is analyzed. the major inducements of lpg vessel under high temperature are as follows : 1 ) sudden falling of pressure on valve opening ; 2 ) material strength falling of vessel wall, which is caused by high temperature of vessel wall ; 3 ) thermal stress that is caused by non - uniform temperature of vessel wall
武漢理工大學碩士學位論文? ?論文最後分析了高溫環境下液化氣容器爆炸的事故機理，即高溫環境下液化氣容器爆炸的主要誘因為： 1 ）閥門打開時的壓力驟降； 2 ）容器壁溫度過高，導致容器壁的材料強度降低； 3 ）容器壁的溫度不均勻引起的熱應力。The results show that at the initial stage, the temperature difference between internal and external wall surfaces is considerable and the temperature distribution is not uniform ; the initial stage belongs in dangerous time period because of the considerable temperature stresses
試驗結果表明：加載初期儲罐內外表面溫差較大且分佈很不均勻，是罐壁產生較大溫度應力的危險時間段。In this paper, i have analyzed the distortion of continuous rigid frame bridge at the condition of temperature uniform change by displacement method and finite element method computer aided design program - sap91. it included : the distortion and inner force condition at the bottom of single pier when it is consolidated, the distortion and inner force condition of thin double piers - rigid frame bridge ; the distortion and inner force condition of thin double piers - rigid frame bridge when the consolidation is elastic consolidation and confinement adopted different rigidity factor ; and the inner force condition of thin double piers - rigid frame bridge when the distance of piers is different
本文利用位移法和結構有限元電算程序sap91 ，對連續剛構體系橋梁在受到均勻溫變情況下：墩底固接單柱墩、雙薄壁墩連續剛構橋；墩底彈性固接時的雙薄壁墩連續剛構橋採用不同轉動約束剛度系數情況；以及雙薄壁墩墩間距不同的連續剛構橋梁的受力情況進行了分析和比較。Thermally driven comparison of small single - cyclic channel and small multi - cyclic channel in gravitation field is performed through experiments and numerical simulations. the results show that the change of temperature at walls of the heat end minishes and the temperature distribution uniforms with the addition of the cyclic channels. and the ratio of the circuit ’ s height ( h ) to the distance between cooled and heat end ( w ) has effect on heat transfer
本文首先採用實驗與數值模擬相結合的方法對重力場下單循環和多循環微小通道內流體的熱驅動進行比較研究，發現隨著循環通道的增加，熱端壁溫起伏變化減小，溫度分佈逐漸均勻化，而且通道高度與冷熱端間距的比值h / w的變化對通道換熱也有影響。The gelation with complete cooling time of 40min had a high yields and encapsulation efficiency, and the process may be contrplled. the micropcms was stable and its diameter was uniformity. the thermal profile of microcapsule was not affected by the ratio of gelation, but the thermal was not good enough
結果表明：以明膠-阿拉伯樹膠為壁材制備的相變儲熱微膠囊平均粒徑均勻；壁材完整，包覆效果較好；熱分析顯示，相變儲熱微膠囊具有自調溫功能，但明膠-阿拉伯樹膠為壁材的微膠囊熱穩定性較差。分享友人
