A scaled version of the APT70 drone rotor, typical of small to medium UAV rotors, was tested
in a 9-meter-high cold chamber for a wide range of icing parameters. The drone rotor used …

Successful icing/de-icing simulations for rotorcraft require a good prediction of the
convective heat transfer on the blade's surface. Rotorcraft icing is an unwanted …

Local errors in the geometrical description of the ice front are amplified in multistep
simulations over conformal meshes due to the coupling of aerodynamics, water …

This paper presents a novel level-set-based approach to model evolving boundary
problems for in-flight ice accretion. No partial differential equations are solved as in the …

Drones and UAVs are gaining worldwide popularity and are now considered a popular
choice for both military and commercial applications. Icing poses tremendous safety and …

Purpose Responsible for lift generation, the helicopter rotor is an essential component to
protect against ice accretion. As rotorcraft present a smaller wing cross-section and a lower …

To predict flight icing more widely and practically, an ice accretion numerical framework that
incorporates both the water droplet splash and the ice crystal sticking is developed. By …

Purpose Numerical simulation of icing has become a standard. Once the iced shape is
known, however, the analyst needs to update the computational fluid dynamics (CFD) grid …

This paper presents a mesh generation strategy that facilitates the numerical simulation of
ice accretion on realistic aircraft configurations by automating the deformation of surface and …

A grouping-circular-based (GCB) greedy algorithm is proposed to improve the efficiency of
mesh deformation. By incorporating the multigrid concept that the computational errors on …
