Description
technical field [0001] The invention relates to an oil throwing disc type fuel atomization experiment system and an operation method, belonging to the field of fuel atomization experiments. Background technique [0002] Combustion efficiency has an important impact on the dynamic characteristics of aero-engines and pollutant emissions, and the quality of fuel atomization is the key to determining combustion efficiency. The particle size of the fuel droplets atomized by the nozzle is distributed in the micron level, and the broken fuel droplets increase the contact area with the air, thereby improving the combustion efficiency. Commonly used atomization methods include pressure atomization, centrifugal atomization, pneumatic atomization, and oil thrower atomization. [0003] Oil flinger atomization is a kind of rotary atomization. The high-speed rotating main shaft sprays fuel from the radial direction. The fuel is broken under the action of centrifugal force and generates t...
