Conical Two-Phase Swirl Flow Atomizers—Numerical and Experimental Study

This paper presents the results of numerical simulations for developed and discussed conical two-phase atomizers with swirl flow, differing in ratio height chamber to its diameter. Experiments were carried out SAN-1 HS/DS = 1 SAN-2 4 atomizers. The study was conducted over a range Reynolds number liquid ReL (1400; 5650) gas ReG (2970; 9900). Numerical calculations performed use computational fluid dynamics (CFD), which verified on basis experimental data. Based analysis studies influence operational parameters changes atomizer geometry generated spray demonstrated. As flow rate increased decreased, angle increased. Higher velocity values greater turbulence occur center spray. inside determines nature obtained. influences air core formed atomizer, this atomization effect. not only confirm studies, but also provide additional information internal external flow.
