Whereas streamwise effective slope (surfaces in this study can lead to diminished levels of
outer-layer similarity in both mean flow and turbulence statistics, which is attributed to …

The skewness of the roughness height distribution is one of the key topographical
parameters that govern roughness effects on wall-bounded turbulence. In this paper …

Abstract The Greenland Ice Sheet (GrIS) mass balance is examined with an Earth system/ice
sheet model that interactively couples the GrIS to the broader Earth system. The simulation …

While blade surface roughness arising from in-service wear and/or the manufacturing
process greatly affects aero-thermal performance, the detailed underlying physical …

In this study, the resolution dependence of the simulated Greenland ice sheet surface mass
balance (GrIS SMB) in the variable-resolution Community Earth System Model (VR-CESM) …

High-fidelity simulation of transitional and turbulent flows over multi-scale surface roughness
presents several challenges. For instance, the complex and irregular geometrical nature of …

Reservoir expansion over the last century has largely affected downstream flow
characteristics. Yet very little is known about the impacts of reservoir expansion on the …

Abstract The streamwise effective slope (\({\rm ES} _x\)), which is the mean absolute
streamwise gradient of the roughness, is considered to be a key parameter in predicting the …

Spinning up a highly complex, coupled Earth system model (ESM) is a time consuming and
computationally demanding exercise. For models with interactive ice sheet components, this …

Understanding the influence of surface roughness on drag forces remains a significant
challenge in fluid dynamics. This paper presents a convolutional neural network (CNN) that …
