The distribution of droplet sizes produced in a microfluidic T-junction is modeled using the gamma probability distribution. The proposed model is validated using physical insight from the hypothesized mechanism of droplet breakup and statistically using the Anderson–Darling test. Where signal-to-noise ratio is low and the gamma distribution does not hold, an alternative probabilistic description is used to estimate the true mean of droplet sizes. In addition, a new correlation is developed to relate mean droplet sizes to T-junction inlet flow rates and dispersed-phase viscosity.
