Paul and all;

I haven't responded to the postings related to my rad installation as I have
been traveling.  However; I appreciate the input.  The limited perspective
of a couple of photos don't tell the story, but the main points raised are
valid ones; a) the space downstream from the radiator; b)the potential for
an eddie in the inlet diffuser (and the possible eddie that recirculates
through the radiator), c) the shape of the inlet scoop, and, d) the effects
of the boundary layer.  I have considered all of these previously in the
light of the sometimes conflicting requirements, and will reconsider them
some again in light of the comments; and when the concept is actually flown.

amount of diffusion is required for each case.  I suggest some reasonable
lip radii and a splitter to separate the boundary layer.

Meanwhile; the boundary layer effects remain the one that concerns me the
most; and Jeff; could you please tell me more about what a boundary layer
"splitter" is, and what it would look like.
