The Role of Vortex Stretching in Drag Reduction of Polymer-Laden Turbulent Flow
Wouter J. T. Bos, Xuan Shao, Tong Wu +1
An addition of polymers can significantly reduce drag in wall-bounded turbulent flows, such as pipes or channels. This phenomenon is accompanied by a noticeable modification of the…
