1. 1. Accurate physical and numerical modeling of complex vortex phenomena over delta wings

   Författare :Simone Crippa; Arthur Rizzi; Stefan Wallin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational fluid dynamics; CFD; vortical flow; delta wing; aerodynamics; flow physics; steady; unsteady; Vehicle engineering; Farkostteknik;

   Sammanfattning : With this contribution to the AVT-113/VFE-2 task group it was possible to prove the feasibility of high Reynolds number CFD computations to resolve and thus better understand the peculiar dual vortex system encountered on the VFE-2 blunt leading edge delta wing. Initial investigations into this phenomenon seemed to undermine the hypothesis, that the formation of the inner vortex system relies on the laminar state of the boundary layer at separation onset.

3. 2. Advances in vortical flow prediction methods for design of delta-winged aircraft

   Författare :Simone Crippa; Arthur Rizzi; James Luckring; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; delta wing; slender wing; aircraft; vortex; VFE-2; CAWAPI; HISAC; Vehicle engineering; Farkostteknik;

   Sammanfattning : This thesis covers the field of vortex-flow dominated external aerodynamics. As part of the contribution to the AVT-113 task group it was possible to prove the feasibility of high Reynolds number CFD computations to resolve and thus better understand the peculiar dual vortex system encountered on the VFE-2 blunt leading edge delta wing at low to moderate incidences.
