Jan Bartl has a phd degree in experimental fluid mechanics from NTNU in 2018, with a focus upon wind turbines. He is an associate professor at Department of Mechanical and Marine Engineering at HVL (Western Norway University of Applied Sciences). His research is about making wind turbines more efficient and maintainable by design and optimization through socalled multi rotor concepts. Simulation of wind effects plays a key role. At the end of the episode he also comments on what he thinks is required in the bigger picture to roll out wind power faster, and the outside is outside his own research area.
