Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments (2022)
Journal Article
Bastianon, E., Hope, J. A., Dorrell, R. M., & Parsons, D. R. (2022). Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments. Earth surface dynamics European Geosciences Union, 10(6), 1115-1140. https://doi.org/10.5194/esurf-10-1115-2022

Shallow tidal environments are very productive ecosystems but are sensitive to environmental changes and sea level rise. Bio-morphodynamic control of these environments is therefore a crucial consideration; however, the effect of small-scale biologic...

Mixing in density- and viscosity-stratified flows (2022)
Journal Article
Allen, P. A., Dorrell, R. M., Harlen, O. G., Thomas, R. E., & McCaffrey, W. D. (2022). Mixing in density- and viscosity-stratified flows. Physics of Fluids, 34(9), Article 096605. https://doi.org/10.1063/5.0108337

The lock-exchange problem is used extensively to study the flow dynamics of density-driven flows, such as gravity currents, and as a canonical problem to mixing in stratified flows. Opposite halves of a domain are filled with two fluids of different... Read More about Mixing in density- and viscosity-stratified flows.

Time‐Domain Implementation and Analyses of Multi‐Motion Modes of Floating Structures (2022)
Journal Article
Sheng, W., Tapoglou, E., Ma, X., Taylor, C. J., Dorrell, R., Parsons, D. R., & Aggidis, G. (2022). Time‐Domain Implementation and Analyses of Multi‐Motion Modes of Floating Structures. Journal of Marine Science and Engineering, 10(5), Article 662. https://doi.org/10.3390/jmse10050662

The study of wave‐structure interactions involving nonlinear forces would often make use of the popular hybrid frequency–time domain method. In the hybrid method, the frequency‐domain analysis could firstly provide the reliable and accurate dynamic p...
