[FlyRotary] Re: Performance coatings- bearing damage?
In
anticipation of the new turbo, I am considering ways to improve coolant
cooling. Besides the obvious more air, more ducting, more radiator; I have
been again toying with the idea of a heat exchanger. This time coolant to
fuel. The plan would be to use a typical oil/water exchanger but use fuel
instead of oil. I would use the fuel on the way back to the tank, and the
coolant after it has already been cooled by the radiator. The fuel would
then go back to the nice metal tank of the RV.
I am
looking for input on the implications of heating the fuel. I expect it
would reach max temps of about 190 (usually a little cooler) but
quickly cool once in the tank. Can the fuel tolerate that temp without
vaporizing? It will probably expand in the tank but I don't expect that
will occur faster than it is used up. I have no guess as to what temp will
become steady state for the fuel pumped out of the tank. My guess is that
it will not be much warmer than normal, but a slight increase in temp may help
with vaporization.
The
last question is how much will it cool the coolant. My hope is about 10
deg but I doubt it will be quite that much. I know others have considered
using the fuel to cool (Tracy) and I would appreciate your
thoughts.
