Summary

 

Overview

I use high performance computing to simulate flows in porous media and understand how reaction processes alter flow behaviour. This is particularly important in carbon-storage (CCS) operations where mixtures injected into underground reservoirs become acidic and alter the flow properties of the rock.

My principle aim is to develop tools to model and understand these processes. We use lattice Boltzmann (LB) modelling to compute flow distributions through large 3D images of rock pore-structures, and couple this with transport and reaction models to determine how these structures are altered through dissolution.

These models are then scaled up using high performance computing, in particular GPU clusters and applied to large systems. Then these can be used as predictive tools to optimise CCS operations.
