A couple more photos of the Truncated
Streamline ducts. The volume of the duct with the smaller opening is
filled with foam, so should that prove too small an inlet, the foam an easily be
removed to opening the duct up to the same profile as the one with the larger
opening - just in case {:>)
Its very interesting how the wall shape of the
streamline duct "uses" the higher pressure profile (sort of like a bell shape
curve - with the higher pressure toward the center axis of the duct) to
resist the centrifugal force trying to move the airflow away (separate) from the
wall. This results in better pressure recovery than the older Sinusoidal
shaped ducts which flexed the walls outward actually making the separation
problem worst by distributing the pressure over a larger volume of space
therefore reducing its effectiveness in preventing flow separation at the
wall.
