K-EPSILON´s customized tools can be used to provide tangible benefits to a range of renewable energy applications, including wind, wave, tidal, and solar applications.

K-EPSILON provides hydrodynamic, aerodynamic hydrodynamic, aerodynamic and fluid-structure modeling services appropriate for these applications :
-Power curves
-Unsteady gust response
-Behavior in waves
-Device wake interaction
-Rotor blade fluid-structure interaction
-Solar panel flutter or vortex-induced motions

K-EPSILON is active in the renewable energy market in two areas:

- Enhancement of existing systems
- Strategic

Existing units are being reviewed and studied with the focus on how to improve their energy capturing efficiency with respect to wind, wave and tidal applications or their structural efficiency and cost for solar panel arrays..
In addition, K-EPSILON has a program to invest in new areas like wave, wind, current, and other sources of energy. In this program, K-EPSILON is starting to test the efficiency of a new type of energy generation system. Indeed, The K-EPSILON solution and expertise team are looking for research partners in this domain. K-EPSILON Computational Fluid Dynamics (CFD) Flow modeling software and customized tools can be used to provide tangible benefits to a range of renewable energy applications.  K-EPSILON provides modeling services appropriate for these applications.

Few examples .

FSI on solar panel suspending
FSI on cable suspended solar panels,  company TSE (2020/ 2023)
K-EPSILON collaborated with TSE between 2020 and 2023 to realize fluid-structure interaction simulations to characterize the vibration of the system induced by the vortex shedding on the solar panels for certain panel inclination angles .
FSI on a tidal turbine
R&D Project, PHD K-EPSILON / INSA Corentin Lothode ( 2020)
Fluid-structure interaction solutions adapted to turbine blade vibration. Computation were performed with K-FSI (coupling between FINE™/Marine and K-Struct). The video shows the unsteady mesh deformation around the blades performed by K-FSI. The results were published in Journal of Ocean Engineering.
Darrius tidal turbine : Project URABAILA
URABAILA R&D FUI PROJECT with Bertin Technologie (2016)
Unsteady RANSE computation of a Darrius vertical axis tidal turbine, with sliding grid rotating mesh,
This study was part of the FUI 15 project “URABAILA” with Bertin Technologie. The tidal turbine shown in this video is designed by Bertin Technologie.
Tidal turbine for SABELLA
RANSE computation on Sabella
K-EPSILON performed 2D and 3D RANSE computations on the horizontal axis tidal turbine developed by the company Sabella. The performance in aligned and oblique flow was investigated. .
