<p>This dataset contains experimental, calculated and numerical (CFD) data on capillary jet breakup in a vibration granulator (prilling), supporting the optimization of melt granulation processes.</p> <b>The dataset includes:</b> <ul> <li><b>Factorial design:</b> 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><b>Mathematical model (Maple):</b> input parameters, dimensionless numbers (Oh, We, Re, Ca), linear stability results and droplet diameters by five theoretical approaches for a urea melt jet (D_j = 1.2 mm, u = 4.35 m/s, T ≈ 133 °C), with sensitivity analysis.</li> <li><b>Experiment and CFD (water):</b> 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> <p>Combined vibration excitation reduced the COV of droplet diameter from 18.6–20.6% to 6.3–8.4%, approaching monodisperse droplet formation.</p> <p><b>Setup:</b> vibration granulator with a disc actuator (diameter 100 mm, thickness 1 mm), vibration amplitude 100 µm, excitation frequencies 220–780 Hz.</p>
