The jet burner is a machine which requires the systematic consideration in design from the disintegration of liquid fuel to the generation of super-sonic jet flame. Until now the optimum operating condition has been experimentally determined and it has been a troublesome work. This paper reports the new method to determine the optimum operating condition of air-kerosene jet burner.
Based on the equation of Pereverzev, which showed that mass exchange rate was dependent on the relative velocity between droplet and surrounding gas. the authors calculated the required length of the rnmbustion chamber.
This calculation made it possible to determine all configurations starting from five initial conditions, which were flow rate of kerosene, injection pressure, spray angle, air-fuel ratio and combustion chamber pressure. The method of calculation and some results are graphically presented and the comparison with the experimental data is made as well.
