High-Speed Imaging to Quantify the Transient Ice Accretion Process on a NACA 0012 Airfoil
Ice accretion on aircraft wings poses a performance and safety threat as aircraft encounter supercooled droplets suspended in the cloud layer. The details of the ice accretion depend on the atmospheric conditions and the flight parameters. The icing process on the wing consists of a complex interaction of water deposition, surface water transport, and freezing. The aerodynamics affect the water...

متن کاملAn Experimental Investigation on the Unsteady Heat Transfer Process Over an Ice Accreting NACA 0012 Airfoil
The in-flight ice formation and accretion are highly dependent on weather conditions that essentially affect the heat transfer capability. When the temperature is sufficiently cold, the heat transfer is adequate to remove all of the latent heat from the collected water. The rate of rime ice accretion is controlled by the droplet collection efficiency. Otherwise, when the heat transfer is inadeq...
متن کاملPrediction of Airfoil Characteristics WithHigher Order Turbulence
The assessment of turbulence model performance in predicting ow elds that are directly relevant to industrial needs has become increasingly important. In aerodynamics , many problems exist for which the performance of some turbulence models is ambiguous at best and incorrect at worst. The application of many diierent turbulence models to a particular problem is a lengthy process that can lead t...
متن کاملWind tunnel effects on ice accretion over aircraft wings
Reference ice accretion experiments are reproduced numerically using the simulation framework PoliMIce to investigate solid blockage effects and wall-model boundary layer interaction at the wall-model juncture. The open-source OpenFOAM software is applied to the computation of the aerodynamic flow-field and of the trajectories of water droplets. The thickness of the iced layer is then determine...
