In-flight Ice Accretion Prediction Code

Abstract

The phenomenon of in-flight icing may affect all types of aircraft. The paper deals with thedevelopment of the computational wing airfoil ice accretion prediction code Ice. Presented codeversions enable computational rime ice and glaze ice accretion prediction on single and multi-elementairfoils in acceptable time of solution. There are presented results of rime ice and glaze ice accretionpredictions and compared with current ice accretion prediction codes. Various cases of predicted iceshapes are shown in dependence of air temperature. The latest Ice code version enables to solvesystem of several airfoils. The example of ice prediction on the wing airfoil with a slotted flap is shown fortwo angles of deflection.
