The effects of swirling airflow and divergence angle on the atomizing performance of an airblast atomizer were studied. Six different atomizers having three kinds of blade angle swirlers and three kinds of exit divergence angle have been tested, and the results have been analyzed. It is concluded that the swirling airflow and the divergence angle have little influence on the atomizing performance. Therefore atomizers may be designed chiefly according to the flow pattern needed in the combustor.
