Håkan Nilsson

Professor vid Chalmers, Mekanik och maritima vetenskaper, Strömningslära

Mitt huvudsakliga forskningsområde är inom vattenkraft, där jag har 2-3 doktorander som finansieras av Svenskt VattenkraftCentrum (www.svc.nu). Vi fokuserar på vattenströmning och kavitation i inlopps- och utloppstunnlar, spiralen, ledskenepassagen, löphjulet, och sugröret. Vi studerar även kylluftflödet i elgeneratorerna. Vi utvecklar och validerar numeriska metoder och modeller (exempelvis rotor-stator-metoder och turbulensmodeller), och tillhandahåller exempel och riktlinjer för hur man på bästa sätt gör dylika numeriska studier. Vi utför även experimentella mätningar.Jag är även aktiv i doktorandprojekt och exjobb i andra områden, såsom:* Beräkning av fibrer i luftströmning* Beräkning av flödet i flödesmätare* Strömning och värmeöverföring i TIG-svetsning* Strömning i aortan (experimentellt och numeriskt)* Naturlig konvektion vid fria vätskeytor med ytnedsmutsning* Strömningen i en centrifugalpump* Strömningen i virvelgeneratorerna i Timisoara och Stuttgart* Strömningen i blodådror i nacken vid whiplash-rörelse* CAD- och beräkningsnätgenerering från datortomografi Jag handleder även många små projekt i projektkurser.Alla CFD-beräkningar utförs med OpenFOAM, som är öppen källkod. Jag är aktiv i internationella grupperingar som använder och utvecklar OpenFOAM, exempelvis OpenFOAM Turbomachinery Working Group. Jag deltar i OpenFOAM Workshop Committee, som planerar en årlig internationell OpenFOAM Workshop.
