Om
Forskning
Min forskning er fokusert på eksperimentelle målinger av turbulente strømninger. Noen temaer jeg arbeider aktivt med er:
- Transport av CO₂ og O₂ fra luft til vann ved hjelp av turbulens
- Generering av turbulens ved høye Reynolds-tall (high Reynolds number).
- Miljøinspirerte problemstillinger innen fluidmekanikk.
- Effekten av turbulens på ulike geometrier (f.eks. vingprofiler, bygninger og vindturbiner).
- Turbulente grenselag.
- Vindassistert fremdrift av skip.
Jeg er professor med ansvar for NTNUs vindtunnel og luft-vann-kanal.
