高圧力下における炭化水素燃料液滴の燃焼

抄録

Experimental studies were made of combustion and evaporation of fuel droplets in high pressure environments. The burning rate constant, evaporation constant, life time and droplet temperature were measured for various kinds of liquid hydrocarbon fuels. As results, with increasing ambient pressure the burning rate constant increases and reaches the maximum value in the vicinity of the critical pressure of the fuel, and then decreases as the pressure increases further. From the comparison between the pressure dependences of the burning rate constant and the evaporation constant at various ambient temperatures, it is suggested that the evaporation phenomena during both combustion and evaporation in a high temperature environment are similar to each other.
