The effect of Schmidt number on gravity current flows: The formation of large-scale three-dimensional structures (2021)
Journal Article
Marshall, C. R., Dorrell, R. M., Dutta, S., Keevil, G. M., Peakall, J., & Tobias, S. M. (2021). The effect of Schmidt number on gravity current flows: The formation of large-scale three-dimensional structures. Physics of Fluids, 33(10), Article 106601. https://doi.org/10.1063/5.0064386

The Schmidt number, defined as the ratio of scalar to momentum diffusivity, varies by multiple orders of magnitude in real-world flows, with large differences in scalar diffusivity between temperature, solute, and sediment driven flows. This is espec... Read More about The effect of Schmidt number on gravity current flows: The formation of large-scale three-dimensional structures.

Equilibrium sediment transport by dilute turbidity currents: Comparison of competence-based and capacity-based models (2021)
Journal Article
Amy, L., & Dorrell, R. (in press). Equilibrium sediment transport by dilute turbidity currents: Comparison of competence-based and capacity-based models. Sedimentology, https://doi.org/10.1111/sed.12921

Equilibrium sediment transport is the condition of zero net entrainment and deposition by sediment-transporting flow (i.e. grade or regime). Here criteria for equilibrium sediment transport, or those used as proxies for equilibrium (for example, onse...

Hydrodynamic efficiency in sharks: the combined role of riblets and denticles (2021)
Journal Article
Lloyd, C. J., Peakall, J., Burns, A., Keevil, G., Dorrell, R. M., Wignall, P., & Fletcher, T. (2021). Hydrodynamic efficiency in sharks: the combined role of riblets and denticles. Bioinspiration&biomimetics, 16(4), Article 046008. https://doi.org/10.1088/1748-3190/abf3b1

We investigate the influence of smooth and ribletted shark skin on a turbulent boundary layer flow. Through Laser Doppler Anemometry the role of riblets in combination with the shark skin denticle is established for the first time. Our results show t...

Observations of large-scale coherent structures in gravity currents: implications for flow dynamics (2021)
Journal Article
Marshall, C. R., Dorrell, R. M., Keevil, G. M., Peakall, J., & Tobias, S. M. (2021). Observations of large-scale coherent structures in gravity currents: implications for flow dynamics. Experiments in Fluids, 62(6), Article 120. https://doi.org/10.1007/s00348-021-03217-4

Density driven flows, also known as gravity currents, comprise a head, body, and tail. Yet whilst the body typically forms the largest part of such flows, its structure remains poorly understood. In this work, experimental data gathered using particl... Read More about Observations of large-scale coherent structures in gravity currents: implications for flow dynamics.
