Flow Behavior in Side-View Plane of Pitching Delta Wing [PDF]
In the present investigation, a delta wing which has 70° sweep angle, Λ was oscillated on its midcord according to the equation of α(t)=αm+α0sin(ωet). This study focused on understanding the effect of pitching and characterizing the interaction of vortex

Simplified model for helical vortex dynamics in the wake of an asymmetric rotor
Helical vortex systems, such as those found in the wakes of wind turbines, helicopter rotors and propellers, are subject to instabilities that lead to pairing between adjacent vortex loops.
