"Cylinder"	325 KB, JPG	'0510.02	Quasi-Karman Vortex Street.    This was a first attempt at producing a vortex street.  Two vortices appear to be shedding off the top of the cylinder and two off the bottom.  It has been suggested that better vortex development could be had with a wider channel (here ~ 4x the cylinder diameter).  Efforts at improving the upstream laminar flow and flow rate are also in process.
Angle of Attack: 0°	329 KB, JPG	'0511.21	Hydrofoil at 0° Angle of Attack.    The upstream flow is far from laminar.  Much effort has been put into improving this and more needs to be done.  Nonetheless, this photo should give one an idea of the flow around this object.    As one might expect, with this 0° angle of attack, the flow is virtually undisturbed and fully attached to the surface of the hydrofoil.
Angle of Attack: 10°	331 KB, JPG	'0511.28	Flow separation indicated at ~1/3 cord.
Angle of Attack: 40°	335 KB, JPG	'0511.28	More flow separation.
Angle of Attack: 60°	327 KB, JPG	'0511.28	Flow separation fully developed.    Note colors coming off the leading and trailing edges.  The absence of colors in that region between the leading and trailing edges indicates very little flow in that area.  Since the flow rate is very slow here (~1 cm/sec), the turbulence one might expect in this area is not occurring.
