Inception of ice accretion by ice crystal impact [PDF]
Journal of Physics: Conference Series, 2016 In this experimental and theoretical study the ice accretion phenomena on a heated cylinder in Braunschweig Icing Wind Tunnel are investigated. The ice crystal size, velocity, the liquid-to-total mass ratio are accurately controlled. The evolution of the cylinder temperature, the time required for the inception of the ice accretion, and the ice ...

Sensitivity Study of Ice Accretion Simulation to Roughness Thermal Correction Model
Aerospace, 2021 The effects of atmospheric icing can be anticipated by Computational Fluid Dynamics (CFD). Past studies show that the convective heat transfer influences the ice accretion and is itself a function of surface roughness.

Quantification of ice accretions for icing scaling evaluations [PDF]
36th AIAA Aerospace Sciences Meeting and Exhibit, 1998 The comparison of ice accretion characteristics is an integral part of aircraft icing research. It is often necessary to compare an ice accretion obtained from a flight test or numerical simulation to one produced in an icing wind tunnel or for validation of an icing scaling method.

Numerical Research of an Ice Accretion Delay Method by the Bio-Inspired Leading Edge
Aerospace, 2022 The accumulation of ice on aircraft is a typical meteorological issue. The ice accretion on the wing’s leading edge can cause an earlier stall and significantly increase the safety risks.

Ice Accretion on Rotary-Wing Unmanned Aerial Vehicles—A Review Study
Aerospace, 2023 Ice accretion on rotary-wing unmanned aerial vehicles (RWUAVs) needs to be studied separately from the fixed-wing UAVs because of the additional flow complexities induced by the propeller rotation.

Crystal Structure of Ice Accreted on an Ice Substrate [PDF]
Journal of Glaciology, 1987 AbstractThin ice deposits, grown on a prismatic ice substrate and the first layers of large deposits grown about a cylindrical ice collector, are studied. Experiments were performed at 30 m s–1 wind speed and Ta near –20° C. Progressive structural changes in thin accretions with time of water-injection were observed, when the substrate temperature was ...

Ice Accretions on Structures [PDF]
Journal of Glaciology, 1977 AbstractThree basic areas of ice accretion are discussed: (i) the motion of the (supercooled) droplets in air up to collision with the icing object, (ii) the net growth rates, and (iii) the heat balance of an icing cylinder. The weakness of presently used approaches to establish collision efficiency and possible improvements are outlined.
