This site-wide search returns results for all documents and events in Tethys Engineering, prioritizing the best matches. Partial word matches are returned (e.g. "engineer" finds "engineering"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys Engineering features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

So et al.
This study evaluates the accuracy of using the opensource wave energy converter modeling WEC-Sim code to model an oscillating water column (OWC) as a virtual point absorber. WEC-Sim is a free, open-source hydrodynamic modeling extension of MATLAB/Simulink, and is designed primarily for ease of use and the modeling of oscillating body wave energy converters (e.g., point absorbers). Oscillating…

The floating oscillating surge wave energy converter (FOSWEC) is a wave energy converter that was designed, built, and tested to develop an open-access data set for the purpose of numerical model validation. This paper details the experimental testing of the 1:33-scale FOSWEC in a directional wave basin, and compares experimental data to numerical simulations using the wave energy converter…

Lawson et al.
Wave energy converters (WECs) are commonly designed and analyzed using numerical models that combine multibody dynamics with hydrodynamic models based on the Cummins equation and linearized hydrodynamic coefficients. These modeling methods are attractive design tools because they are computationally inexpensive and do not require the use of high-performance computing resources necessitated by…

A passive yaw implementation is developed, validated, and explored for the WEC-Sim, an open-source wave energy converter modeling tool that works within MATLAB/Simulink. The
Reference Model 5 (RM5) is selected for this investigation, and a WEC-Sim model of the device is modified to allow yaw motion. A boundary element method (BEM) code was used to calculate the excitation force… - Conference Paper:

Faraggiana et al.
A submerged wave device generates energy from the relative motion of floating bodies. In WaveSub, three floats are joined to a reactor; each connected to a spring and generator. Electricity generated damps the orbital movements of the floats. The forces are non-linear and each float interacts with the others. Tuning to the wave climate is achieved by changing the line lengths so there is a…
