Bakgrunn og aktiviteter
Jeg jobber med vannkraftteknologi, primært knyttet til hjertet av et vannkraftverk; turbinen. Fokusområder er simulering av drift av turbiner, inkludert systemdynamikk i rør og tuneller, rotor-stator fenomener, utmatting og design.
I tillegg er jeg NTNUs representant i EERA Joint Programme Energy Storage (JP ES), og aktivt medlem i Sub-programme 4 Mekanisk lagring i JP ES.
