Autoignition delay time for kerosene

Viento · July 26, 2018, 08:07

Hello. I need some empirical correlation for calculation knock in kerosene-air mixture to get autoignition delay time. (A general case is needed, not only for piston engines.) Can you advise me something?

Douaud and Eyzat correlation is determined for 80<octane number<100. Of course, I can try to make CEL-analogue for ON 38-40 (equivalent of octane number of kerosene), but I dont think, that this is good idea.

This is specialised question on IC engine modelling, not a CFD question. You will need to do your own research in the literature to work that out.
