Conférence midi de Mme Maria Klepikova le 26 sept

La conférence s'intitule : Heat transport in the subsurface: in situ experiments and modelling

 

Résumé :

Understanding heat transport in heterogeneous aquifers is central to many environmental processes and industrial applications, including energy production in geothermal reservoirs, heat storage in the ground, near-field thermal effects in radioactive waste disposal and subsurface urban heat islands. The characterization and modeling of heat transfer in the subsurface is particularly challenging as the existence of heterogeneities in hydraulic properties at all scales induce flow channeling that significantly complicates relevant temperature patterns. While much progresses have been made in characterizing and modeling subsurface heterogeneity in flow and solute transport processes, the effects of multi-scale subsurface heterogeneities on heat transport remains largely an open question.This presentation will focus on the interplay between flow dynamics, solute and heat transport in alluvial and in fractured crystalline aquifers. Case studies will be presented to illustrate the complexity of heat transfer processes in heterogeneous media.
