Claims (15)

1. Hvirvelgenerator til vindmøllevinge omfattende: et fluidprofil (26) omfattende en trykside (30) og en sugeside (32), der strækker sig fra en større aerodynamisk flade (22) af vingen; hvilket fluidprofil (26) danner et hvirvelhul omfattende en sugesidekonkavitet (43A), der er dannet langs mindst en del af fluidprofilets (26) sugeside; hvor hvirvelhullet omfatter en progressiv runding (42) mellem fluidprofilets sugeside (32A) og den større aerodynamiske flade (22), hvor en radius af den progressive runding (42) forøges progressivt fra en frontende (44) til en bagende af fluidprofilet.
2. Hvirvelgenerator ifølge krav 1, hvor i det mindste delen af fluidprofilets sugeside omfatter en konisk flade med et toppunkt i nærheden af en frontende af fluidprofilets sugeside.
3. Hvirvelgenerator ifølge krav 1 eller 2, hvor hvirvelhullet omfatter en distal del af fluidprofilet, der krummer over sugesiden deraf og danner en spændvis sugesidekonkavitet fra den progressive runding til den distale del.
4. Hvirvelgenerator ifølge krav 3, hvor konkaviteten er kontinuerlig fra rundingen til den distale del.
5. Hvirvelgenerator ifølge et af kravene 1 til 4, endvidere omfattende et andet fluidprofil, der omfatter et spejlbillede af fluidprofilet ifølge krav 1 på tværs af et spejlplan mellem de to fluidprofilers sugesider, hvor de to fluidprofiler er adskilt fra hinanden og divergerer fra hinanden fra forsiden til bagsiden, og hvor de progressive rundinger på de to fluidprofilers sugesider konvergerer mod hinanden fra forsiden til bagsiden langs den større aerodynamiske flade.
6. Hvirvelgenerator ifølge et af kravene 1 til 5, endvidere omfattende en runding mellem en bagkant af fluidprofilet og den større aerodynamiske overflade, hvor bagkantrundingen omfatter en forhøjning, der spænder over bagkanten og den større aerodynamiske flade.

8. Hvirvelgenerator ifølge krav 7, hvor den kontinuerlige kontur danner hvirvelhullet med en konkavitetsakse, der divergerer fra indfaldsvinklen mod det frie strømningsflow og krummer mod en retning af det frie strømningsflow med mindst 5 grader.
9. Hvirvelgenerator ifølge et af de foregående krav, hvor fluidprofilet omfatter en relativt tyk roddel, der er fastgjort til den større aerodynamiske flade, og en relativt tynd forkant, der strækker udad og er vinklet tilbage fra en frontende af roddelen, hvor fluidprofilets forkant kun har et enkelt toppunkt set i tværsnit langs i det mindste størstedelen af forkanten.
