摘要
从理论和实验两个方面分析了突扩管流动 .结果表明 ,在有压管流的突扩管段内 ,一方面沿程有机械能损失 ,另一方面由于下游管径的增大 ,造成动能减少和势能增加 ,受这两方面共同影响的测压管水头 ,无论何种工况 。
Theoretical and experimental study on the pipe flow with sudden enlargement pipe is made in this paper.The result shows that the piezometer tube water head of sudden enlargement pipe for a pipe flow is always increased with whatever operating mode, even though there are two contrary factors affecting it.
