Study on Characters of Kerosene/O2 HVO Jet
The aviation kerosene and O2 were ignited in the chamber in order to obtain the distribution characteristics of the high velocity jet, which was accelerated and sprayed from the exit. The distribution characteristics of the temperature and velocity on the axis at the exit were obtained by calculation The distribution of the field was obtained by FLUENT numerical simulations. Measuring the temperature and velocity at different distances with particle tester and metal-melt method, the jet characteristics will change with the change of kerosene O2 ratio The results show that the temperature is about 2 800 K and the velocity is about 2 150 m/s at the exit. The temperature and velocity reduce with the distance increase What's more, with the increase of oxygen-enriched degree, the temperature and velocity in the jet field reduce obviously.
Key words： aviation kerosene; O2; jet; numerical simulation; oxygen-enriched degree
