sci.homogenization-pressure-droplet Calculator
Calculates droplet size after high-pressure homogenisation using the Kolmogorov-Hinze model: d_32 = C × (σ/ρ)^0.6 × ε^(−0.4). Droplet size ∝ pressure^(−0.6) — doubling homogenisation pressure reduces droplet size by 35%; typical dairy homogeniser operates at 150–250 bar producing d < 2 µm.
Inputs
D1 Um
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
P Mpa
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
D Min Um
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Eta Efficiency
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Results
resulting droplet diameter d₂ (μm)
The computed diameter -- twice the radius.
size reduction ratio
The proportional relationship between two quantities.
specific energy input (kJ/kg)
Sample size or count used in the calculation.
d₂ = d_min + (d₁-d_min)·exp(-η·P)
Sample size or count used in the calculation.
typical d₂ (dairy homogenization)
The value at the specified point or condition.
energy efficiency
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
