Ice Accretion on Cylinders for Different Droplet Distribution Spectrums
Numerical simulations of several different low droplet inertia cases have been conducted using multiphase computational fluid dynamics(CFD)based approach A comparison has been made with experimental data where the results show significant differences in predicted values of ice accretions for different droplet distribution spectrums.This can be explained by differences between drag and inertia forces within different bins in distribution spectra,influencing local collision efficiency and maximum impingement angles values,in different simulations with constant operating parameters.Furthermore,some effects,like ice accretions on the back of cylinders have been observed in CFD simulations,which cannot be explained within the inviscid theory of ice accretion.The explanation of those can be found using viscous flow assumptions.
