Abstract

The influence of transition on the flow pattern and pressure distribution on VFE-2 was investigated by implementing the three-equation k-ω-γ transition model into DDES method (DDES-Tr). The DDES based on full turbulence (DDES-FT) is involved for comparison. For the attached flow, the vortex structure and flow pattern are largely affected by the transition exists on the leading-edge. Both the primary vortex and inboard vortex are captured by DDES-Tr, while the inboard vortex disappears in the DDES-FT, indicating the importance of transition in simulating the attached flow on VFE-2.
