    2010-1-1 · Since the kinetic energy of the particles gets larger with the increase of the evaporation temperature, the nuclei possess excess energy and coalesce after collisions. Evaporation temperature is also connected with the vapor pressure. Lower evaporation temperature corresponds to lower vapor pressure, yielding smaller particles . Inert gas type also plays an important role on the particle size.

    The boil-off rate of H 2 is typically 0.4%/day for 50 m 3 tanks, 0.2% for 100 m 3 tanks and 0.06% for 20 000 m 3 tanks (using double-walled vacuum-insulated spherical Dewars). Loss of hydrogen due to boil-off is a problem, although recent work indicates that for the most recent tank designs, venting occurs only in the case of infrequent driving.

    It exhibits a much lower value than that of E100 at 10 °C but with a steep rise, reaching the level of E100 by 40 °C, hence it was not considered appropriate to extrapolate to lower temperatures. Nevertheless, it is clear that cold temperature effects on supressing in-nozzle cavitation and out-of-nozzle breakup and evaporation are expected to be stronger for hydrous ethanol.
