Abstract Wells turbine is an important component in the oscillating water column (OWC) system. Thus, many researchers tend to improve performance via experiment or computational fluid dynamics (CFD) simulation, which cheaper. As CFD method becomes more popular, lack of evidence support parameters used during simulation a big issue. This paper aims review models applied for OWC Journal papers fr...

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...

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...

Optical wireless communication (OWC) using intensity-modulation and direct-detection (IM/DD) has a channel model which possesses unique features, due to the constraints imposed on input. The aim of this tutorial is overview results capacity IM/DD channels with input-independent Gaussian noise as OWC channels. It provides reader an entry point topic, highlights some major contributions in area. ...

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...

Reconfigurable intelligent surfaces (RIS) have been recently introduced to optical wireless communication (OWC) networks resolve skip areas and improve the signal-to-noise ratio at user's end. In OWC networks, RIS are based on mirrors or metasurfaces. Metasurfaces evolved significantly over last few years. As a result, coding, digital, programmable, information metamaterials developed. The adva...

We describe a poreto reservoir-scale investigation of wettability variation and its impact on waterflooding. We use a three-dimensional pore-scale network model of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully predict experimentally measured relative permeability data for the water-wet case, and demonstrate that the model captures experime...
