While ice formation in aviation jet fuel has been a serious
concern in the aviation industry in terms of safety, icing in jet
fuel has poor understood. The ice formation in the fuel delivery
system might be highly affected by hydro-thermal conditions
such as cooling rate, flow condition, and etc. This study
investigated the effects of hydro-thermal environments on ice
crystallization. Ice formation tests were conducted under various
temperatures, cooling rates, and flow conditions. The jet fuel was
cooled down to -38 ℃ with different cooling rates and flow
conditions. The formed ice particles in jet fuel were sampled and
observed in a cold room. The various shapes of ice crystals were
found according to the hydro-thermal condition.
