Abstract

The influence of ice crystals in an airflow on evolution of run-back ice on the surface of the wing model is numerically investigated for the conditions of experiment in an icing wind tunnel. The results confirm that a change in the mass of ice deposits upon introducing crystals into the flow observed experimentally is associated with absorption of some mass of ice crystals by the water film formed on the surface of a solid at low flow velocities and with film splashing at higher flow velocities. In the first case, the mass of the run-back ice increases; in the second case, it decreases.
