Hi guys,
If you can arrange true *counter flow* you can get the exit air hotter than the exit water. My understanding of Todds setup is that it is similiar to mine -- two evaporator cores, in cross flow arrangement.
Counter flow. Would that be where the water enters at the rear of the
radiator and flows to where the air enters? I keep toying with the idea of a finned tube, running between the
floorboard and the belly skin. I have 3" or so, give or take, running
from the firewall to the middle of the plane, where it then opens up
completely. I'd just have to make an opening about 9" wide, and build a
channel below the floor. A couple of 3/4" ID tubes would run water back
to a couple EWPs, and then a two more tubes bring it back up front. There would be about 6ft of finned tube running each way.
If I'm understanding what you said above, my theoretical maximum air
temperature at the exit would be the mid-point temperature of the water
in the 'radiator'?
