According to rigorous procedures, an experimental study was carried out to investigate the effects of jet exit velocity, flow direction, fluid subcooling and nozzle diameter on hysteresis of boiling heat transfer with impinging circular submerged jets of highly - wetting liquids
摘要系統地研究了液體在圓形斷面噴嘴浸沒射流作用下沸騰熱滯后與射流沖擊速度大小、液體流動方向、液體過冷度和噴嘴直徑等因素的影響。 -
Simulating experiment on casing - cutting with submerged abrasive water jet
磨料射流切割井下套管的模擬實驗研究 -
The existing results about scour hole was summarized. experiments was made about the influence of aeration on scour, the dynamic pressure on the original riverbed and the scouring hole bottom, and the influence of aeration on the dynamic pressure and the velocity of submerged jet. scour was simulated by numerical model
在總結前人研究成果的基礎上，試驗研究了摻氣對基巖沖刷破壞的影響；基巖沖刷過程中沖坑底部脈動壓強隨沖坑深度的增加而變化的特性；摻氣對沖坑未形成前河床底部及基巖沖刷坑底部脈動壓強的影響；摻氣對射流軸線流速變化的影響等。 -
Experiments about the influence of aeration on the velocity of the submerged jet was made. it has been proved that the main reason of the influence of aeration on scour is the more rapid decrease of the velocity of the submerged velocity. 6
對基巖的沖刷進行了數值模擬，選取臨近底部的結點處的壓強（壓力水頭值）與結點處水深的差值，再與結點處垂直於底面方向的速度分量的0
