Abstract
A physical and mathematical model of ice accretion on an axisymmetric body rotating in an airflow containing ice particles with various sphericities is proposed. Upon impact with the surface, a portion of the particle mass is deposited. A numerical study is performed to determine the ice shape, accounting for possible detachment by centrifugal force. The effects of viscosity and turbulence of the carrier gas on the processes under consideration are taken into account.
