New approach in classification of integrable hydrodynamic chains is established. This is the method of the Hamiltonian hydrodynamic reductions. Simultaneously, this approach yields explicit Hamiltonian hydrodynamic reductions of the Hamiltonian hydrodynamic chains. The concept of reducible Poisson brackets is established. Also this approach is useful for non-Hamiltonian hydrodynamic chains. The...

The hydrodynamic description of trickle flow is a complex field of study. One of the main contributors to the complexity is the existence of multiple hydrodynamic states (MHS). As early as 1978, Kan & Greenfield reported different pressure drop and holdup readings for the same liquid and gas feed rates. The study revealed that the flow history experienced by the bed determined the specific hydr...

A floating oscillating water column (OWC) wave energy converter (WEC) supported by mooring lines can be modelled as an elastically OWC. The main objective of this paper is to investigate the effects frequency ratio on performance OWC (oscillating column) devices that oscillate either vertically or horizontally at two different mass ratios (m = 2 and 3) through two-dimensional computational flui...

Hydrodynamic conditions can influence the distribution and abundance of aquatic species in many ways, including directly through disturbance and resource delivery, and indirectly by altering environmental cues and species interactions. In coral reef ecosystems, corallivory is an important top-down control of coral populations, while water motion can enhance coral performance via autotrophic and...
