The computed flow field for the aerator of Kárahnjúkar spillway. (a) Computed contours of velocity field of a more optimized design for the aerator of Kárahnjúkar spillway. Inset: vortical structures in the ventilation zone. (b) Instantaneous configuration of bubbles in a spillway with ski jump aerator. Here, = 0.62 m. (c) Air concentration distribution versus in the aeration region. Here, right triangles, squares, left triangles, and diamonds represent the air concentration at the sampling ports S₁, S₂, S₃, and S₄, respectively.
