Primary objective: Investigate the pressure and velocity field at flexible operating conditions of Francis turbine.

Secondary objectives: (1) Study pressure and velocity field in the vaneless space at start-stop conditions of the turbine. (2) Study pressure and velocity field in the vaneless space at no-load conditions of the turbine.

Anker Moi Pedersen is writing master thesis on transient operation of Francis turbine. Anker started master thesis in January 2025, and he will focus on numerical simulations with dynamic mesh. Anker aims to move the guide vanes from no-load position to the part-load position of the Francis-99 turbine in the Waterpower laboratory. Anker investigate the unsteady flow conditions in the vaneless space that will enable experimental investigations using PIV later.

Mikal Høie Tjølsen is writing master thesis on transient operation of Francis turbine. Mikal started master thesis in January 2025, and he will focus on numerical simulations with dynamic mesh. Mikal aims to move the guide vanes from the part-load to the best efficiency point of the Francis-99 turbine in the Waterpower laboratory. Mikal investigate the unsteady flow conditions in the vaneless space that will enable experimental investigations using PIV later.
