HGS RESEARCH HIGHLIGHT – Numerical simulation of geothermal energy transfer beneath exothermic waste rock piles

This publication, co-authored by Jasmin Raymond, René Therrien, Louis Gosselin, and René Lefebvre, which investigates how geothermal energy can be harnessed beneath exothermic waste rock piles to improve the performance of ground-coupled heat pump systems. This study leverages HydroGeoSphere (HGS) to simulate coupled subsurface fluid flow and heat transfer, addressing long-standing challenges in quantifying how enhanced subsurface temperatures generated by sulfide mineral oxidation can reduce the required length and number of ground heat exchangers.

HGS RESEARCH HIGHLIGHT – Saltwater Circulation Driven by Shoreline Curvature in Coastal Aquifers

This publication co-authored by Xuan Yu, Lanxuan He, Rongjiang Yao, Zexuan Xu, George Kourakos, Jie Yang, and Franklin W. Schwartz, which investigates how shoreline curvature influences saltwater circulation, freshwater–saltwater mixing, and submarine groundwater discharge (SGD) in coastal aquifers. This study leverages HydroGeoSphere (HGS) to perform fully three-dimensional, variable-density groundwater flow and salt transport simulations, addressing long-standing limitations of two-dimensional coastal aquifer models that neglect along-shore and lateral flow processes.
