Ice accretion compositions in ice crystal icing

open access: yesInternational Journal of Heat and Mass Transfer, 2023
Ice crystal icing is a major hazard in aviation from the perspectives of aerodynamic deterioration, flight safety and operability. To counter this challenge, existing ice prediction tools require more accurate modeling of sticking efficiency of glaciated ice crystals on heated substrates. As part of the present study, icing wind tunnel experiments have

Experimental Investigation on Glaze Ice Accretion and Its Influence on Aerodynamic Characteristics of Pipeline Suspension Bridges

open access: yesApplied Sciences, 2020
Pipeline suspension bridges may experience ice accretion under special atmospheric conditions, and the aerodynamic characteristics of the bridges may be modified by the ice accretion.

Making the Solar System

open access: yesThe Astrophysical Journal, 2023
We model the early stages of planet formation in the solar system, including continual planetesimal formation, and planetesimal and pebble accretion onto planetary embryos in an evolving disk driven by a disk wind.

Influence of Ice Accretion on Stratospheric Airship in the Non-Forming Ascending Process

open access: yesAerospace, 2022
Ice accretion on stratospheric airships, which affects the net buoyancy and reduces the ascent speed, thereby leading to component failure and further necessitating flight termination, has received considerable attention.

Experimental Study on Ice Accretion of Aviation Jet Fuel Tube

open access: yesAerospace, 2022
Ice accretion on the inner surface of a fuel tube can fall off and potentially block the filters and small orifices, which thereby restricts the fuel flow to the engines during the long flying of the aircraft in cold conditions.

Effects of accretion flow on the chemical structure in the inner regions of protoplanetary disks [PDF]

open access: yes, 2008
We have studied the dependence of the profiles of molecular abundances and line emission on the accretion flow in the hot ($\ga 100$K) inner region of protoplanetary disks. The gas-phase reactions initiated by evaporation of the ice mantle on dust grains

The Formation of Uranus and Neptune in Solid-Rich Feeding Zones: Connecting Chemistry and Dynamics [PDF]

open access: yes, 2009
The core accretion theory of planet formation has at least two fundamental problems explaining the origins of Uranus and Neptune: (1) dynamical times in the trans-Saturnian solar nebula are so long that core growth can take > 15 Myr, and (2) the onset of

Separating gas-giant and ice-giant planets by halting pebble accretion [PDF]

open access: yes, 2014
In the Solar System giant planets come in two flavours: 'gas giants' (Jupiter and Saturn) with massive gas envelopes and 'ice giants' (Uranus and Neptune) with much thinner envelopes around their cores.

Numerical study of ice accretion inside an inertial particle separator

open access: yesAIP Advances, 2022
The inertial particle separator (IPS) installed before a helicopter engine runs the risk of ice accretion. This paper describes a numerical study of ice accretion inside an IPS.
