Hi Ed,
 
Pretty slides.  They SEEM authoritative but who gets to write the "rules"?  :-)  In other words, where is the rest of the data.  I completely agree that a streamline duct is better than the conventional duct, and that separation needs to be avoided.  But do you have any data comparing a restricted neck style to a regular streamline duct?

Once again, the only "creative" bit of thinking on my part was the pinched duct in order to cope with the limitations of having a very small area for a duct.  All the rest of the credit belongs to K&W and Horner as well as few others.
 
 
Ed
