GB/T 41770-2022 Test method for liquid fuel injection characteristics based on backlight imaging technology
3 Terms and Definitions
The following terms and definitions apply to this document:
3:1
Microscopic characteristic parameters used to characterize droplets formed after liquid fuel injection breakup:
Note: including droplet velocity and droplet diameter:
3:1:1
droplet velocity dropletvelocity
The velocity of droplets formed after liquid fuel injection breaks up:
3:1:2
Droplet diameter dropletdiameter
The diameter of the droplets formed after liquid fuel jet breakup:
3:2
Doppler effect Doppler effect
When the wave source and the observer move relative to each other, the frequency received by the observer is different from the frequency emitted by the wave source:
3:3
Using the Doppler effect, it is a test system that simultaneously measures the droplet velocity and droplet diameter:
3:4
Measurement body probevolume
In the phase Doppler analyzer, the test space formed by the intersection of multiple laser beams:
