Investigation of flows in a hydraulic bulb turbine - BulbT

该项目是2007年成立的液压机械联盟的一部分，该联盟的目的是更好地了解低水头水轮机的水力特性。该联盟总部设在拉瓦尔大学，合作者是参与水轮机设计或运营的领先公司。 该项目是该联盟的第二个项目，包括测量和数值模拟小型灯泡涡轮机中的流动。实验测量在拉瓦尔大学的液压机械实验室进行，数值模拟由工业合作伙伴和研究生与拉瓦尔大学的数值流体力学实验室合作进行。这两种互补的方法将提高对涡轮机中非定常现象的理解。合作伙伴用于设计或分析的数值模拟的质量将得到提高，这是项目预期的结果。这些知识将导致灯泡水轮机的设计具有更好的动态性能。最终，公用事业公司将受益于更可靠的涡轮机，减少维护停机时间，并延长机器寿命。所有这些因素都导致了灯泡水轮机发电的优化。

This project is part of the Consortium on Hydraulic Machines inaugurated in 2007 which aims at achieving a better understanding of the hydraulic behaviour of low-head turbines. The Consortium is based in Université Laval, and collaborators are leading companies involved in hydraulic turbine design or operation. The project, the Consortium's second, consists in measuring and numerically simulating the flow in a small-scale bulb turbine. The experimental measurements are performed in Université Laval's Hydraulic Machine Laboratory and numerical simulations are conducted by both industrial partners and by graduate students in collaboration with Université Laval's Numerical Fluid Mechanics laboratory. The two complementary approaches will improve understanding of unsteady phenomena in turbines. The quality of the numerical simulations used by the partners for design or analysis will be enhanced, which is an anticipated outcome of the project. This knowledge will lead to the design of bulb turbines with improved dynamic behaviour. Ultimately, utilities will benefit from more reliable turbines, reduced maintenance downtime, and increased machine life. All of these elements lead to the optimization of power generation by bulb turbines.
