BTW; Paul, another data point for your cooling system data bank is my
in-cowl and scoop. The second radiator in the wing root is doing next to
nothing, yet my coolant temps are fine with one 11 x 16 x 2.5" radiator, and
a somewhat P-51 style scoop. It needed internal vanes as well for uniform
flow distribution through the core.

Al
Bulent, Perry Mick and other are cooling fine with no vanes.
Vanes are WW I technology. They are very narrow band devices.
K & M discussed them in a narrow context having to do with
a wall too close to the back side of a core. Move the wall back
a bit and the vanes hurt. Kays & London ignored them completely.
It is far more important to have a properly designed diffuser and a boundary
layer air bleed.

The vanes are needed because off the curvature of the duct. Unfortunately,
all of us have design constraints due to configuration.
But I think you missed the point. That's providing the cooling I need at
about 2 cubic inches of core per HP. Is anyone getting better than that?
Al
Bulents oil cooler duct turns 90 degrees as well.
Are talking about the water radiator? What speed are you going?
What is the size of your rad? What is the OAT?
What is your top speed? Is it cooling at top speed?
Does that include both your rads or just one?
BTW there are no vanes inside a Locheed 1011 S duct for the center engine.
Same goes for Dassault Falcon 50EX.
