Do you really believe this Pete? That frictional factors of air flow
(or water) cause heat buildup in the engine and that's the cause of
overheating? Tell me, do you also go stand naked in screaming winter
storms to warm up from the friction of the snowflakes striking your
skin? The effectiveness, and principle, is the same.
Long before any frictional increase in heat could even be measured, your
Triumph, and its radiator, would have long shreaded themselves in the
Basic engineering Pete is that the Reynolds number increases as the
velocity of the fluids increase in the heat exchanger. The higher the
reynolds number, the greater the heat transfer. If you're not
interested in increasing the rate of heat transfer (ie, the cooling is
already adequate) then you can reduce the size of the heat exchanger, or
That's why stationary equipment has such large radiators, and mobile
equipment has small radiators. The more fluid you move through the heat
exchanger, the more heat you exchange.
To get up to where frictionally induced heat becomes even a faint
factor, the speeds have to be upwards of 1,000mph or so in the air. It
just *isn't* a factor for a Triumph, no matter how fast we'd all love to
believe them to be.
