What is it about?
The paper presents a geometry study of a throttle which is typically used in the surge tank of a high-head power plant. We used the commercial 3D-numerical software ANSYS-CFX and showed basic dependence of the local head losses depending on the flow direction and those parameters. It is particularly useful as a first assumption to design a surge tank, which is in general a very specific task including a lot of different degrees of freedom.

Why is it important?
standardisation of a complex hydraulic structure based on a numerical tool
Perspectives
Helps to reduce the needed time to optimise such a particular hydraulic structure as well as speeds up the first design iterations based on the adaptation of the literature equation. It is also a good show case of the capability of the numerical simulation to investigate a wide range of geometries, which would be nearly impossible in a scale model test.
