From silo discharge and granular avalanches to the erosion of granular beds, granular materials play a central role in many industrial and environmental processes. While significant advances have been made in understanding the statics and dynamics of cohesionless grains, the role of interparticle adhesion, which fundamentally alters bulk rheology and transport mechanisms, remains elusive. In […]

The theory of homogenization provides a systematic approach to the derivation of macroscale constitutive laws, obviating the need to repeatedly resolve complex microstructure. However, the unit cell problem which defines the constitutive model is typically not amenable to analytical solution. It is therefore of interest to learn constitutive models from data generated by the unit […]

The growth in wind energy is driving a need to understand how wind turbines perform under a range of atmospheric conditions. Under stably stratified conditions, for example, wind turbine wakes can persist for long distances and impact the performance of downwind turbines. Additionally, variations in surface topography, from shallow depressions to steep mountains, can deflect […]
