This paper deals with a new combined concept consisting of an oscillating water column (OWC) device and offshore wind turbine for the multi-purpose utilization renewable energy resources. The is supported by monopile foundation, attached OWC coaxial foundation. Within chamber, exterior shell foundation are connected four vertical stiffening plates. Correspondingly, whole chamber divided into eq...

The evaluation of the overall performance is important to design an oscillating water column (OWC) device. A generic OWC model was tested experimentally in a wave flume, which employed real impulse turbine be connected with air chamber. performances under free-spinning mode irregular scenarios were analyzed. Effects electronic resistance acting as external loads drive train on primary-stage, se...

Most experimental research on land-fixed Oscillating Water Column (OWC) systems assume that the OWC-water wave interaction happens with waves propagate normally towards device. However, angle of incidence can determine performance OWC, in particular period at which device resonates. In this study, an investigation to examine regular, oblique, water a land-fixed, thick-front wall OWC terms its h...

By using molecular dynamics simulation, we have investigated systematically the feasibility of continuous unidirectional water flux across a deformed single-walled carbon nanotube (SWNT) driven by an oscillating charge outside without osmotic pressure or hydrostatic drop. Simulation results indicate that the flux is dependent sensitively on the oscillating frequency of the charge, the distance ...

The hydrodynamic response of a land-based oscillating water column (OWC) wave energy converter under various irregular conditions is investigated numerically. Based on the potential flow theory, two-dimensional fully nonlinear numerical flume (NWF) developed to model characteristics using time-domain higher-order boundary element method (HOBEM). inner-domain sources and JONSWAP spectrum used ge...

Oscillating water column (OWC) device has the potential application in field of harbor agitation mitigation/coastal protection. In this paper, we present a theoretical study on hydrodynamic performance novel coastal structure, which combines conventional harbor/coast-based single-chamber OWC and surface-piercing perforated barrier. Based linear flow theory, semi-analytical model for wave intera...

We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effects in a field enclosure experiment. To accentuate the vertical light gradient, enclosures had black walls, resulting in a euphotic depth of only 3.7 m. All enclosures were placed in a well-mixed w...

The present study investigated cross-media transport between both the sediment and the water column and between the water column and the atmosphere, to understand the role of each compartment as a source or a sink of polycyclic aromatic hydrocarbons (PAH) in southern California, USA, coastal waters. Concentrations of PAH were measured in the atmosphere, water column, and sediment at four water-...

We detected very strong coupling between the oscillating concentration of ATP and the dynamics of intracellular water during glycolysis in Saccharomyces cerevisiae. Our results indicate that: i) dipolar relaxation of intracellular water is heterogeneous within the cell and different from dilute conditions, ii) water dipolar relaxation oscillates with glycolysis and in phase with ATP concentrati...
