The paper presents the concept of new swirl inserts. An empty two-phase swirl flow atomizer, and three atomizers with inserts were designed, manufactured and tested. The tested atomizers did not differ in terms of their geometric dimensions, with the only variable being the type swirl chamber filling. Flow resistance and spray angle values were analysed for all the evaluated structures. It was shown that the presence of a swirl insert does not significantly increase flow resistance, but instead results in larger spray angles. Taking into account the values of flow resistance and spray angles, the best design solution turned out to be the set of inserts No. 2.
