摘要：

Investigation of hydro-turbine runner flow on a full-scale test rig consisting of a spiral casing, a stator, guide vanes, and a runner is difficult due to high cost and labor intensity. Therefore, an approach to modeling the inlet velocity profile of a hydro turbine draft tube is proposed that significantly reduces the cost of testing. In this approach, the draft tube inlet flow is modeled using a special swirl apparatus which is a combination of two swirlers: fixed and rotating. The paper presents the results of analytical calculation of the vane shape that provides a given velocity distribution corresponding to the optimal operation of the hydro turbine.
