Description
Summary:For studying ice accretion on aircraft and helicopter airfoils, a modified model of the mass and heat transfer on icing surface was first proposed based on the classical Messinger model. Then an approach for predicting ice accretion on multi-element airfoils was set up through introducing the interpolation calculation of airflow field around the multi-element airfoils. Considering the equivalent thermal power from anti-ice system, a method of the prediction of ice accretion under anti-ice situation was proposed. In order to study the prediction of ice accretion on helicopter rotor, a numerical simulation method combining the computational fluid dynamics （CFD） technique with helicopter aerodynamics theory was set up. The agreement between the results of numerical simulation and the experimental data indicates that the model and methods proposed in this paper are feasible and effective, and that they can lay the foundation of the research on the dynamics in icing condition and design of anti/de-ice system.
