Droplet Collection Efficiency Regularity of NACA0012 Airfoil Based on the Eulerian Method

Obtaining droplet collection efficiency (DCE) is vital for icing numerical simulations. A impact model based on the Eulerian two-phase flow was established in this work to analyze influence of different incoming parameters DCE. Then, mathematical regularity DCE distribution explored using parametric description, and functional relation between condition accomplished. The results showed that calculated NACA0012 two-dimensional cylinder matched well with test data. velocity size, rather than liquid water content (LWC) flow, affected significantly. under conditions normalized same form peak maximum position. had a highly normal distribution, which expressed good Reynolds number diameter. Regularity can greatly reduce amount calculation improve accuracy, plays positive role prediction problem.
