Abstract
Reducing the skin-friction drag in turbulent wall flows has seen a growing interest in recent years, owing to potential energetic and environmental advantages. Passive techniques (like riblets) are not yet in widespread use, notwithstanding their applicative appeal; most of the strategies currently under investigation are active techniques. One of the simplest and most interesting amongst active approaches is the oscillating-wall technique [1], where the wall moves according to: w (t)= Asin.(1)File in questo prodotto:
