Effect of variable pitch on flow around a helically twisted elliptic cylinder

We propose a new geometric disturbance called a variable pitch helically twisted elliptical (VPHTE) cylinder that was obtained by combining helically twisted elliptic (HTE) and asymmetric geometries for passive flow control. We confirmed that the new geometric disturbance reduces the drag and lift f...
