A theoretical and experimental investigation is conducted to study the two-phase turbulent structure in a planar mixing layer with polydispersed drops. Mean and fluctuating velocity components, drop number density, as well as drop size distribution were measured with nonintrusive diagnostics of the two-component phase Doppler particle analyzer. Complete initial conditions required for theoretical calculation were also provided with measurements. Theoretical investigation is made with the Eulerian-Lagrangian formulation. Turbulent dispersion effects are numerically simulated using the Monte Carlo method. The well-defined experimental data have been used to assess the accuracy of the Eulerian-Lagrangian model. The comparisons show that the theoretical predictions, based on the Eulerian-Lagrangian model, yield reasonable agreement with the experimental data.
