We investigate the flow over smooth (non-ribletted) shark skin denticles in an open-channel flow using direct numerical simulation (DNS) and two Reynolds averaged Navier-Stokes (RANS) closures. Large peaks in pressure and viscous drag are observed at... Read More about Multi-fidelity modelling of shark skin denticle flows: insights into drag generation mechanisms.

Density stratification controls the bedform phase diagram of saline-gravity currents versus open-channel flows (2023)
Journal Article
Ohata, K., de Cala, I., Dorrell, R. M., Naruse, H., McLelland, S. J., Simmons, S. M., & McCaffrey, W. D. (in press). Density stratification controls the bedform phase diagram of saline-gravity currents versus open-channel flows. Sedimentology, https://doi.org/10.1111/sed.13075

Sedimentary bedforms such as ripples and dunes are generated both by river flows and sediment-laden gravity currents. Gravity current deposits are usually parameterized using existing bedform phase diagrams which are based on data from laboratory exp...
