Experimental Confirmation of Water Column Natural Resonance Migration in a BBDB Device
نویسندگان
چکیده
Experiments were conducted with a Backward Bent Duct Buoy (BBDB) oscillating water column wave energy conversion device with a scaling factor of 50 at HMRC at University College Cork, Ireland. Results were compared to numerical performance models. This work experimentally verified the migration of the natural resonance location of the water column due to hydrodynamic coupling for a floating nonaxisymmetric device without a power conversion chain PCC present. In addition, the experimental results verified the performance model with a PCC of the same nonaxisymmetric device when both floating and grounded.

Optimal Resistive Control Strategy for a Floating OWC Device
A resistive control strategy to optimize pneumatic power for a floating OWC device is presented. This strategy utilizes a linear, frequency-domain performance model that links an oscillating structure to air-pressure fluctuations with a Wells Turbine in 3-dimensions. An array of field points defining the interior free surface allows hydrodynamic parameters relating to the fluctuating air-pressu...

Natural gas usually contains significant amounts of acid gases when it is extracted from underground reservoirs. Therefore, it must be treated by appropriate processes to remove these acidic components. In this study, the simultaneous absorption of carbon dioxide and hydrogen sulfide from natural gas into diethanol amine solution was simulated using CFD. Absorption process was performed in a we...
