SPRAY CHARACTERIZATION OF LIQUID/GAS COAXIAL INJECTORS WITH THE CENTER LIQUID SWIRLED
摘要
Some results of an investigation to characterize sprays generated by liquid/gas coaxial injectors with the center liquid swirled are described. This injector type is similar to an air-assisted pressure swirl injector. Without gas flow it becomes a pressure swirl injector. This injector type is currently being considered/or use in a liquid oxygen/gaseous hydrogen rocket combustor. Spray characterization results were obtained from photographs, a pat-ternation system, and a phase Doppler particle analyzer (PDPA).
The results of this investigation are summarized below:
- Spray angle increased with increasing liquid mass flow rate and decreasing gas mass flow rate.
- A symmetric hollow-cone spray was produced.
- Spray structure was similar to the spray structure of a pressure swirl injector.
