The dataset includes: <ul> <li>Factorial design: 22 full factorial experiment on the influence of actuator plate position (5–30 mm) and liquid column height (120–450 mm) on the actuator operating frequency.</li> <li>Mathematical model (Maple): input parameters, dimensionless numbers (Oh, We, Re, Ca), linear stability results and droplet diameters by five theoretical approaches for a urea melt jet (Dj = 1.2 mm, u = 4.35 m/s, T ≈ 133 °C), with sensitivity analysis.</li> <li>Experiment and CFD (water): high-speed images and CFD results for single-point and combined (dual-frequency, f2/f1 = 2.05) vibration excitation, including Sauter mean diameter (SMD) and coefficient of variation (COV).</li> </ul> Combined vibration excitation reduced the COV of droplet diameter from 18.6–20.6% to 6.3–8.4%, approaching monodisperse droplet formation. Setup: vibration granulator with a disc actuator (diameter 100 mm, thickness 1 mm), vibration amplitude 100 µm, excitation frequencies 220–780 Hz.Experimental dataNumerical simulation dataCalculated dataThe dataset consists of 8 CSV tables (comma-separated, UTF-8, decimal point), 9 PNG images and README.txt with a detailed description of each file, abbreviations and methodology.
