Computer Modeling of Time-Dependent Rime Icing in the Atmosphere,

reportActive / Technical Report | Accession Number: ADA126404 | Open PDF

Abstract:

A numerical model of rime ice accretion on an arbitrary two-dimensional airfoil is presented. The physics of the model are described and results are presented that demonstrate, by comparison with other theoretical data and experimental data, that the model predictions are believable. Results are also presented that illustrate the capability of the model to handle time-dependent rime ice accretion, taking into account the feedback between the ice accretion and the airflow and droplet trajectory fields.
