Wake-induced vibrations are considered distinctively different from well-known vortex induced vibrations where bluff body structures vibrate under vortex shedding in the wake of flows passing through them.
An analytical model is presented for predicting the vortex shedding noise generated from the wake of axial flow fan blades.
This negative pressure and the single-wake behavior of flow over the row of buildings provide explanations for the observed interference effects.
Then, too, ECT, which causes the brain to go into seizure, was back in fashion for treatment-resistant depression after going off the radar in the '60s and '70s in the wake of "One Flew Over the Cuckoo's Nest".
The mechanism of drag reduction is caused by the combined effect of forcing frequency and oscillation amplitude due to the modification of wake flow at high frequency and the delay in flow separation, while the fluctuating lift force slightly increases at a high frequency caused by the small-scale vortex shedding in synchronous with the rotational oscillation.
Particular emphasis is placed on interpretation of wake flow survey results and the correlation to measured forces.
No obvious effects of wake flow control could be observed by placing the vortex generators near the rear end of the trailer model.
Results reveal that the flame leading edge dynamics displays a peak response around St = 0.5 suggesting that the leading edge motion is mainly due to the advection of appropriate ignition conditions as a result of the excitement of the wake recirculating flow.
Comparisons of the details of the wake flow structure as well as quantitative comparisons of wind comfort and shelter characteristics up to 10H downstream of fences, where H is the fence height, are also presented.
At times this summer, one could cross the normally deep river at some points in Bastrop and be soaked only to the waist; in the wake of heavy rains, the flow has returned but is sure to recede again.
