  • Influence of the liquid viscosity on air core size in the pressure swirl atomizer was investigated. And theoretical analysis model was established in a control volume with the conservation law of angular momentum in the particles system. Eventually, the semi-theoretical prediction formula was derived, and used to calculate air core size and spray cone angle. In addition, validity of the prediction formula was verified by experimental data under different operation conditions. Results show that the present prediction formula can availably and accurately calculate air core size and averaged spray cone angle, exhibiting a prediction uncertainty of ±13% for air core diameter calculation and from -20% to 6% for spray cone angle determination.
