Влияние противодавления в камере сгорания на характеристики факела распыливания за форсунками

Abstract

The paper describes effect of the chamber pressure, or more exact, the air density in the pressure chamber on fuel spray characteristics. Has been calculated the film behind pressurized fuel injectors swirl. The droplet size increases with increasing of the air density in the pressure chamber. The coaxial air flow has effect on the SMD of the droplets within the pressure swirl spray. Calculation results show that with an air flow will decrease film thickness values if backpressure is increasing.
