What is it about?
Ice accretion due to water droplets is a well known issue. However, ice accretion due to solid or mixed phase cloud particles is a relatively new topic. These cloud particles may cause ice to accrete especially on heated surfaces and on engine internal components. For prediction Extended Messinger model is used for ice accretion due to water droplets. In this study Extended Messinger Method is further extended to be used for solid/mixed phase cloud particles as well.

Why is it important?
It is shown in this study that further Extended Messinger Model increased the accuracy of the validation comparisons. Moreover, calibrated erosion and impingement models yielded significant improvements.
Perspectives
As it is stated in the article the introduced new model will be a promising alternative and many researchers in this field will make use of it.
