DNS Study on Physics of Late Boundary Layer Transition
Chaoqun Liu, Ping Lu
This paper serves as a review of our recent new DNS study on physics of late boundary layer transition. This includes mechanism of the large coherent vortex structure formation, sm…
Numerical Study on Mechanism of Small Vortex Generation in Boundary Layer Transition
Ping Lu, Chaoqun Liu
The small vortex generation is a key issue of the mechanism for late flow transition and turbulence generation. It was widely accepted that small length vortices were generated by…
Numerical and Experimental Studies on the Separation Topology of the MVG Controlled Flow at M=2.5
Qin Li, Yonghua Yan, Ping Lu +3
In this paper, the implicitly implemented LES method and fifth order bandwidth optimized WENO scheme are used to make comprehensive studies on the separation topology of the MVG co…
LES Study on the Mechanism of Vortex Rings behind Supersonic MVG with Turbulent Inflow
Yonghua Yan, Caixia Chen, Ping Lu +1
In this study, we investigate the interaction between vortex rings behind MVG and the oblique shocks in the MVG controlled ramp flow at M=2.5 and Req=5760. Implicit large eddy simu…
Numerical Study on Mechanism of Multiple Rings Formation
Ping Lu, Yonghua Yan, Chaoqun Liu
In this paper, the flow around each ring-like vortex is investigated by high order DNS including first sweep, first ejection, second sweep, second ejection, positive spike, momentu…
