And experimental study on the heat transfer performance and pressure drop characteristic of the process of bubbling evaporative cooling are carried. as there are so little attention and studies on the process bubbling evaporative cooling about heat transfer in the world at present, this paper mainly deals with the effects of the different bare tower velocity, weir height, heat flux density and plate perforation geometries on the heat transfer coefficient and the pressure drop of the process of air flowing
由於目前國內外對鼓泡蒸發冷卻過程在換熱方面的關注和研究較少,本文對不同空塔速度、不同堰高、不同熱流密度、多孔板的不同幾何尺寸對換熱系數及空氣流動過程阻力的影響進行了實驗研究及理論分析,總結了本實驗條件下換熱及阻力的實驗關聯式。With the increasing of weir height, the pressure drop increases. and it is independent of bare tower velocity and plate dimension. the correlation before was corrected as follows : pl 3911z this paper analyzed the heat transfer coefficient between the outer wall of heat tubes and cooling water
堰高越高,換熱系數越大;在鼓泡范圍內,空塔速度越大,換熱系數越大;在本實驗條件下,熱流密度在10kw / m2附近換熱系數達到最大值。Relativel ~ ~ matlab language is more powerful than oilier computing language, especially in computation fluid mechanics, it helps to simply draw charts of vortex, stream function, velocity, pressure, and the amount of work can be extremely reduced, and the program coniplving can also be controlled easily
得到空化數的分佈以後,進而分析流場內空泡的運動軌跡,最後得到空泡半徑在流場內隨壓力的變化關系曲線,以及在流場內空泡半徑沿壓力最小點的分佈規律。The paper is on how to set up lab platform of vapour spewing to uppercooling water surface to coagulate directly and to observe and analyse which vapour coagulate on the water surface, the results enable people to know the security system of nuclear power. the range of the pressure parameters of prz is from 0. 2mpa to 0. 6mpa, and the range of the initial temperature parameters of cmt is from 23. 5 to 78. 5, all of the testing points are 30 and there are fifty thousand testing data. many results of vapour spewing to uppercooling water surface vertically to coagulate can get. for example : coagulating can make the water of cmt surge forcefully when vapour spews to uppercooling water surface, too many vapour - bubbles come into being and strike the water of cmt owing to rupture continually, all these will strengthen the surge because of the vapour pressure of cmt
實驗中prz飽和蒸汽壓力變化范圍為: 0 . 2mpa - 0 . 6mpa , cmt中水初始溫度變化范圍: 23 . 5 - 78 . 5 ,實驗中測試工況30個左右,實驗測試數據50萬余個,得出了很多與非能動安全系統相關的蒸汽垂直噴向過冷水表面凝結時的結論:蒸汽垂直噴入過冷水表面凝結時會造成cmt中液面的強烈波動和振蕩,產生大量蒸汽汽泡,汽泡不斷破裂對cmt中液體帶來很大沖擊,勢必引起cmt中液體的振蕩,造成cmt汽空間汽壓不均勻,加強cmt液體的振蕩和波動。The sources are distributed on the bodies and cavity surfaces, a computer program is written to display curves of the pressure coefficient value and velocity value of the supercavity surface
通過在回轉體表面和空泡表面分佈源匯的方法,建立了求解回轉體超空泡表面壓力系數和速度的計算公式。Study of refrigerant void fraction of domestic air - conditioner heat exchanger
