Figure 15: First spatial harmonic of the pressure across each of the three polylines, shown in Figure 4(d), when the blade deflection goes through its range of motion from maximum deflection, through mean deflection and to its minimum deflection position. (a) Polyline at tip of blade (b) polyline between surface and blade tip, and (c) polyline at casing surface.
