The analogy faithfully simulates the unseparated potential flow into the stagnation region of a concave corner, and the infinite velocities over an outside corner. The water takes much longer to travel through the system if it follows a streamline that passes close to a stagnation point. This allows a greater diffusion of dye, which is seen in the slight blurring of streamlines at the lower right-hand corner. Photograph by D. H. Peregrine.
