Modeling binary alloy solidification by a random projection method

Autor: Hélène Mathis, S. Carpy

Publikováno v: Numerical Methods for Partial Differential Equations. 35:733-760

This paper adresses the numerical modelling of the solidification of a binary alloy which obeys a liquidus-solidus phase diagram. In order to capture the moving melting front, we introduce a Lagrange projection scheme based a random sampling projecti

Wind tunnel experimentation of ice particles transport in Martian-like environment

Publikováno v: Europlanet Science Congress 2020

Introduction: The transport of ice by wind plays a major role in the surface mass balance of polar caps [1, 2]. Ice can be redistributed by wind due to (1) transport of ice particles and/or (2) transport of water vapour associated with sublimation/co

International audience; Sublimation waves are periodic, linear and transverse bedforms that grow by sublimation of icy substrates under turbulent winds. They occur in different environments of the Earth and other planets, where the climate is favorab

International audience; Gullies are widespread morphological features on Mars for which current changes have been observed. Liquid water has been one of the potential mechanisms to explain their formation and activity. However, under present-day Mart

The mass and composition of Titan’s massive atmosphere, which is dominated by N2 and CH4 at present, have probably varied all along its history owing to a combination of exogenous and endogenous processes. In the present study, we investigate its f

Role of the global water ocean on the evolution of Titan's primitive atmosphere

Icarus, Elsevier, 2018, 310, pp.127-139. ⟨10.1016/j.icarus.2017.10.048⟩

International audience; During the accretion of Titan, impact heating may have been sufficient to allow the global melting of water ice and the release of volatile compounds, mainly constituted of CO 2 , CH 4 and NH 3. The duration and efficiency of
