... ABSTRACT Application of Wells turbine submersed in water for a wave energy converter (WEC) has been presented here. The WEC is based on a floating U-tube containing water column inside. In response to the wave forces, the U-tube is oscillated and the water column is excited. Energy...

... ABSTRACT This study addresses the limited wave energy conversion performance of oscillating water column (OWC) wave energy converters (WECs) by optimizing chamber dimensions to enhance hydrodynamic efficiency. A 2D numerical wave tank based on CFD simulations is validated through mesh...

... of an air pocket inside the anchor when it is partly submerged has a significant effect on the response of the water column inside the anchor. Estimation of the internal water surface response is very crucial as the slamming load imposed on the internal top surface of the anchor is strongly dependent...

Shear probe and FP07 thermistor are typically installed on the head end of free-falling or free-rising microstructure profiler to detect turbulent fluctuations of velocity and temperature in the water column. Because of the measurement principle of the sensors...

... when designing any deep-water system. Due to the scarcity of measured current speeds and directions along the water column in the past; a vertical current profile was commonly assumed to follow one of the simplified profiles which can be conservative for deep-water systems. In the last decades; several...

... ABSTRACT The dual-chamber oscillating water column (OWC) is considered in this study. The device has two sub-chambers with a shared orifice. A fully-nonlinear numerical wave flume based on the potential-flow theory is applied for the simulation. At various wave conditions, effects...

..., and the majority of the oil would stay on the surface, and accumulate on the shoreline, rather than disperse into water column. Introduction Oil and gas resources, which account for more than 70% of Canada's primary energy production, are of significant national economic importance. The production of crude oil...
