Publikováno v: Developments in Laser Techniques and Fluid Mechanics ISBN: 9783642646041

Effects of fuel temperature on the characteristics of the intermittent-cyclic spray have been experimentally clarified using the phase Doppler anemometer. The spray was initiated from the air assisted fuel injector. The injection frequency was 50Hz,
