From Core to Field: Pattern Selection in Dissolving Fractures
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Chemical erosion governs the evolution of fractures across Earth systems, which manifests in three distinct dissolution patterns. However, how the boundaries between these regimes depend on system scale remains an open question, and no predictive theory has successfully linked laboratory observations to field‐scale behaviors. Here we integrate

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.ABSTRACT In this contribution, we focus on the Reynolds‐averaged Navier‐Stokes (RANS) models and their exploitation to build reliable reduced‐order models to further accelerate predictions for real‐time applications and many‐query scenarios. Specifically, we investigate how machine learning can be employed to enhance the predictive capabilities of the ...
