水平旋转内消能泄水道空腔环流的能动量特性
Hsi-An Chiao Tung Ta Hsueh/Journal of Xi'an Jiaotong University（2004）
Abstract
研究了水平旋转内消能泄水道空腔环流特有的能动量特性.试验观测与分析结果表明:在水平洞的起始段,空腔环流的环向动能沿程急剧减小,进而转化为各占一定比例的环向与轴向动能,并伴随着大量的能量损失;环向的能动量在起始段较大,但在中间段与轴向的能动量比值已接近1,沿程的变化也较小;环向的动能与压能沿程变化相反并互相对应;环向的能量沿程变化规律决定了总能量的沿程变化规律;能量损失与常规的明流或有压泄水道相比大大增加,能量损失机理更为复杂.
