Never heard of anybody looking into that, although it's not something I've
gone looking for. Possibly there might be something to be found in
studies of fuel stability in high-supersonic and hypersonic aircraft
(where friction heating can get fuel in wing tanks pretty hot) -- not
quite the same problem, and often dealt with by using special fuels, but
it might offer some hints.
It would be tricky to get good numbers for something like Jet-A because
there's so much variation in its exact composition.
