Does anybody have any links to technical paper on diffuser rear wing interactions ?

Basically I would like just like to know 3 or 4 rules of thumb

on how the rear wing shapes and diffuser shapes create various interactions between the flows and pressure interactions ?

I don't know anything so I would just like to know the basics? For example how does the slope of the diffuser effect

the situation? Or what does attaching a gurney flap to the diffuser flaps / trailing edge / diffuser vanes do ?

Does the interaction with the rear wing only depend on the distance between the lower wing elements

and output of the diffuser ? What are the basic ways the diffuser and wing flows interact ?

Katz, 30 bucks on Amazon, loads of grqphs, and lots of references. Or steal Milliken's RCVD that has a chapter on aero, probably has the graph you want. Katz is better though.

That being said we've talked about it before here, some searching might be in order.
