摘　　要：进水口立轴漩涡是水利工程和工业管道流动中的常见现象,对企业的经济效益和安全生产影响颇深。为此,从理论分析、模型试验、数值模拟三方面探讨了立轴漩涡的流动机制,总结了漩涡抑制与应用的工程经验,为解决进水口立轴漩涡问题提供参考。Problems of vertical vortices,which arise in the field of water conservancy and industrial pipeline flow,are the key issues associating with economic benefit and safety production of enterprises.Thus,this paper intends to investigate the flow mechanism of vertical vortices from the three aspects of theoretical analyses,experimental tests and numerical simulations.Thus,it provides forward guidance for the vertical vortex problems of water intakes through reviewing the engineering experiences of vortex suppressions and applications.
