In aeronautics, ice accretion can be detrimental to the equipment behavior or can lead to a loss of performance. Ice accretion depends on many parameters (temperature, speed, drop sizes, etc.). The objective of this research work carried out in collaboration with Airbus is to understand the influence of these parameters on ice microstructure, and on its mechanical properties.
The work of the post-doc will take place on the campus of Grenoble. The Researcher will be in charge of:
• Preparing the samples in cold room for their observation by X-ray tomography. These samples will be extracted from blocks of accretion ice obtained under different conditions.
• Acquiring 3D images of the samples by X-ray tomography.
• Implementing or developing tools for image processing and analysis in order to segment the grayscale images and to quantify the relevant microstructural parameters (porosity, porosity gradient, pore size, etc.).
• Implementing numerical simulations (type EF with Abaqus) on REVs (Representative Elementary Volumes) extracted from the 3D images in order to determine the ice mechanical properties (elasticity, etc.).
• Analyzing the results in terms of icing parameters.
Candidates must have strong skills in materials science and mechanics. The work also requires knowledge of experimental characterization methods, particularly X-ray tomography, as well as knowledge of image processing and analysis. The recruited person will have to show a spirit of innovation and autonomy.
The work will take place on the Grenoble campus. It will be supervised by Armelle Philip (IGE), Christian Geindreau (3SR Laboratory) and Frédéric Flin (CNRM / CEN).
