Abstract: A single-side slope-slotted atomizer has been constructed for single-side atomization.The experimental investigation has been carried out on flow pattern and flow resistance of this atomizer.The feature of its low total pressure loss is testified.The information on its atomization field has been collected,from which its atomization characteristics of single-side atomizing field and its fuel atomization density distribution are obtained.It is shown,that this atomizer is one of better atomizers for an afterburner of turbofan aeroengine.
