【摘要】 虹吸原理在工程科学技术中具有广泛的应用。对虹吸非稳态过程进行了数值计算,求解虹吸过程的速度场及压强场,分析了虹吸管道的出水管长度对流速及压强控制的影响,并通过改变出水管长度能很好地控制虹吸过程的流态特性。更多还原

【Abstract】 The siphon principle is used widely in engineering.In this paper the dynamics of the two-dimensional flow in siphon pipe,such as the flow regimes,velocity field and pressure field in the flow pipe,was investigated using a computa-tional fluid dynamics(CFD) model.The effect of the length of outlet pipe was analyzed.The flow regimes can be controlled by the modification of the length of outlet pipe.更多还原
