The opacity of accreted ice

Quarterly Journal of the Royal Meteorological Society, 1975
AbstractA technique which yields quantitative measurements of the opacity of accreted ice deposits is described. This consists of determining the attenuation of a light beam as it passes through a thin section of the deposit, using a photovoltaic cell as the detector. The transmittance of the deposits is related to the air bubble concentration, and the

Crystal size in accreted ice

Quarterly Journal of the Royal Meteorological Society, 1975
AbstractStudies have been made of the crystallographic orientation of 100μm‐radius supercooled droplets frozen on ice substrates whose c‐axis orientations varied from 0 to 90° to the surface normal. For a given droplet temperature and substrate orientation, there is a critical substrate temperature below which a frozen droplet has a high ( > 0·8 ...

FENSAP-ICE: Roughness Effects on Ice Accretion Prediction

41st Aerospace Sciences Meeting and Exhibit, 2003
FENSAP-ICE is a 3D in-flight icing simulation system, built in a modular and interlinked way to successively solve each of flow, impingement, accretion, heat loads and performance degradation via new models based on the Euler/Navier-Stokes equations for the clean and degraded flow and new partial differential equations for the other three icing ...

The Prevention of Ice Accretion

The Journal of the Royal Aeronautical Society, 1936
Flying, in common with all means of transport, is affected by adverse weather conditions, but the necessity of aeroplanes to maintain flying speed introduces a major difficulty of its own. The older forms of transport are able, in the last resort, to evade their difficulties by coming to a dead stop. An aeroplane must, literally, fly in the face of its

Ice Shape Convergence in Multistep Ice Accretion Simulations

Journal of Aircraft
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 impingement, ice accretion, and grid deformation. Small perturbations in the initial phase of ice formation possibly result in dramatically different ice shapes, which can hinder the ...

Proposed modifications to ice accretion/icing scaling theory

26th Aerospace Sciences Meeting, 1988
The difficulty of conducting full-scale icing tests has long been appreciated. Testing in an icing wind tunnel has been undertaken for decades. While aircraft size and speeds have increased, tunnel facilities have not, thus making subscale geometric tests a necessity. Scaling laws governing these tests are almost exclusively based on analysis performed
