| Abstract: | Through setting up high velocity oxygen/air fuel spray the numerical model of field sheds, carrying on the numerical simulation to high velocity fuel spray velocity characteristic and temperature characteristic of particle, its result has announced high velocity oxygen/air fuel spray particle change laws of velocity and temperature. Result of numerical simulation analyses powder grain size influence to velocity and temperature of flame, repeat with different grain size parameter simulation calculate, it has important meaning to accelerate and heat performance of spraying powder. |
