Modelling of hydrate microstructure at the particle size / agglomerate level (microns)
ESR: Khalil Ferjaoui
Start date: October 1, 2018
The objective is to enhance the state-of-the-art micro-scale model of hydrates, µIC, to enable modelling of drying shrinkage in the µIC platform using calculations of local stress. Introductions include:
- information on hydrate properties at a resolution below particle size from from WP 1;
- the reversible and irreversible changes in sub-particle size properties resultant from sorption cycles from WP 2.
