Work Summary

 

I am essentially working with hydropower: experimentally and numerically. Experiments are performed on full-scale machines (Kaplan), models (Kaplan, Francis) and generic test cases (transient, flow unsteadiness). CFD is used to design experiments, understand specific flow phenomena and validate specific turbulence models.

My research is principally concerned with the effects of unsteadiness on the losses, rotor-stator interaction, flow design and flow measurements. Special interest is given to the scale-up formula between model and prototype in hydropower flow, flow control, development of the pressure-time method, trust and quality in CFD. I am partially financed by the Swedish Hydropower Center (www.svc.nu) where I am responsible of the experimental fluid dynamics.
