Analysis of gaseous slip flow and heat transfer in micro rectangular channels 微矩形槽道內的氣體滑移流動和傳熱分析
An experimental investigation on the flow and heat transfer characteristics in rectangular channel with internal netted rib turbulators is conducted 本文對網格式肋化內冷通道在靜止狀態下的強化傳熱與流動阻力特性進行了實驗研究。
It has discovered common faults of various experimental collections and agreed well with the chf data of annular tubes and rectangular channels in water and other liquids 理論式和本實驗及其他文獻的套管,長方形通道的最大熱通量實驗數據進行了比較,在流路狹長的情況時兩者相當吻合。
The model is accurate and of great efficiency . ( 2 ) a numerical experiment concerned with the 3 - d unsteady flow in a rectangular channel driven by tidal forcing at the open boundary has been done ( 2 )模擬了在矩形水域中傳播的潮汐的情況,并與解析解進行了比較,驗證了模型的合理性。
This paper described a cold gas simulation of solid rocket motor with submerged nozzle . a two - dimension model with rectangular channel was designed , which can simulate different flow conditions at three periods after ignition 本文從冷流模擬的角度出發,設計了通道為矩形的含潛入噴管發動機冷流模型,可以模擬發動機工作過程中三個不同時刻的流動狀態。
With the favor of these techniques , the static pressure distribution along the length and the velocity profile at the mini - channel exit were obtained . with the data of more than 500 flow states based on 13 kinds of mini straight rectangular channels that their heights were 0 . 5mm and 1 . 0mm , the effects of characteristic scale , surface roughness and the aspect ratio of rectangular on the characteristics of flow resistance of mini straight channels were studied 采用在沿程測量氣流靜壓分布、在出口測量速度分布的方法,對高度0 . 5mm和1 . 0mm的13個微小直矩形通道的500多個狀態流場進行了測量,研究了特征尺度、表面粗糙度、橫截面寬高比等因素對微小等直通道流動阻力特性的影響。
