Vortex interaction on a LEX configuration

Moo-Ting Chou et al.

Summary: The flow visualization experiments conducted on the NASA TP-1803 model at different angles of attack revealed varying degrees of interaction between the strake and wing vortices, with particularly strong interaction observed at 20 degrees and vortex breakdown at 30 degrees.

An investigation into the nonstationary characteristics of separation-bubble formation on a smooth circular cylinder in the critical transition range

Yi-Huei Lai et al.

Summary: This study investigated the characteristics of separation-bubble formation on a smooth circular cylinder within the critical transition range. Two methods, the sliding-window (SW) method and the peak-valley (PV) method, were used to identify intermittent jumps in the pressure signal, with the PV method found to be less sensitive to small-scale disturbances. The characteristic events identified from the pressure signal were categorized into two types and the count per minute and time scale of these events were used to describe the intermittency of the separation-bubble formation.
