Special Issue Information

Dear Colleagues,

I would like to invite you to publish your next paper in the Energies Special Issue on “New Challenges in Software for Marine Energy Applications”. This Special Issue is focused on the unique challenges faced by marine energy researchers developing software for a specific need, and by developers of broadly applicable open-source marine energy software alike. Marine energy is a new and growing field with a diverse array of technologies. This poses a unique challenge for marine energy software, where one must decide between writing a custom (often proprietary) solution for a specific need, leveraging existing open-source packages, or developing a new software package altogether. These software architecture designs must be weighed against outside factors such as deadlines, funding, and team dynamics, challenges that are faced by the development and application of research software in general. This Special Issue is focused on the unique challenges faced by the marine energy field on the development and application of software.

Authors are invited to submit their original work and survey papers for publication in this Special Issue of Energies. Topics of interest for this Special Issue include, but are not limited to:

Development and application of marine energy software;
Research software and open-source software;
Review of marine energy software;
Marine energy software needs assessment;
Development and application challenges for marine energy software.

We look forward to receiving your contributions. It is recommended to send a tentative title and a short summary of the manuscript to Energies Editor Mr. Louis Liu <[email protected]>.

Towards High-Performance Linear Potential Flow BEM Solver with Low-Rank Compressions

by Matthieu Ancellin, Pierre Marchand and Frédéric Dias

Abstract

The interaction of water waves with floating bodies can be modeled with linear potential flow theory and numerically solved with the boundary element method (BEM). This method requires the construction of dense matrices and the resolution of the corresponding linear systems. The cost of this method in terms of time and memory grows at least quadratically with the size of the mesh, and the resolution of large problems (such as large farms of wave energy converters) can, thus, be very costly. Approximating some blocks of the matrix with data-sparse matrices can limit this cost. While matrix compression with low-rank blocks has become a standard tool in the larger BEM community, the present paper provides its first application (to our knowledge) to linear potential flows. In this paper, we assess how efficiently low-rank blocks can approximate interaction matrices between distant meshes when using the Green function of linear potential flow. Due to the complexity of this Green function, a theoretical study is difficult, and numerical experiments are used to test the approximation method. Typical results on large arrays of floating bodies show that 99% of the accuracy can be reached with 10% of the coefficients of the matrix. Full article

Tanana River Test Site Model Verification Using the Marine and Hydrokinetic Toolkit (MHKiT)

by Emily Browning, Sterling Olson, Rebecca Fao, Adam Keester and James McVey

Abstract

The marine energy (ME) industry historically lacked a standardized data processing toolkit for common tasks such as data ingestion, quality control, and visualization. The marine and hydrokinetic toolkit (MHKiT) solved this issue by providing a public software deployment (open-source and free) toolkit for the ME industry to store and maintain commonly used functionality for wave, tidal, and river energy. This paper demonstrates an initial model verification study in MHKiT. Using Delft3D, a numerical model of the Tanana River Test Site (TRTS) at Nenana, Alaska was created. Field data from the site was collected using an Acoustic Doppler Current Profiler (ADCP) at the proposed Current Energy Converter (CEC) locations. MHKiT is used to process model simulations from Delft3D and compare them to the transect data from the ADCP measurements at TRTS. The ability to use a single tool to process simulation and field data demonstrates the ease at which the ME industry can obtain results and collaborate across specialties, reducing errors and increasing efficiency.
