Renewable Energy

Projects involving rapidly evolving renewable energy technologies are typically varied, sometimes unusual and often involve multiple physics. We have experience with the analysis of wind turbine, composite material and power transmission design and maintenance, focusing on energy efficiency and system reliability.

From testing for the electrochemical performance of a fuel cell stack to optimising the design of biomass reactors and photovoltaic collectors, Ansys engineering simulation software helps improve the reliability of renewable energy systems and reduce the unit cost of energy generated from various technologies. FEA, CFD and electromagnetic capabilities, including coupled analysis, are available to address the development of wind, solar, hydropower, fuel cell and biofuel & biomass energy sources.

To support our Ansys Fluid Dynamics capabilities, we have experience in turbomachinery, micro-climate and wind energy system design, including:

  • 1D design of centrifugal compressor and radial turbine stages
  • 3D aerodynamic / mechanical optimisation and development of component design codes
  • Terrain assessment for wind turbines
  • Investigation of vertical axis (VAWT ) and horizontal axis (HAWT) wind turbine performance under varying wind conditions and blade designs, including turbulence intensities and aero-acoustic effects
  • Fluid-structure (FSI) interaction analysis for blade to undertake fatigue calculations

Our 1D thermal-fluid capabilities enable us t0 assist the design, operation and optimisation of systems and subsystems, accounting for large fluid ranges including homogeneous two-phase, slurries, gasses, liquids, non-condensable mixtures and gas mixtures. Applications include wind power, concentrated solar power (CSP), biomass gasification and geothermal power.

Large energy generation structures, such as wind turbines, require extensive foundation development, sometimes offshore. Clients use PLAXIS geotechnical FEA software to help with the design and validation of piling and slab foundations including the assessment of dynamic loads and ground movement .

The informed use of reliability statistical methods and software helps drive business decisions, maintenance planning and the understanding of availability, system up time, system downtime and MTBF. We have provided ReliaSoft reliability tools and training, including accelerated testing, to renewable energy engineers to help managing the risk of component and system failure and develop well-structured maintenance strategies. One recent consulting project involved life data analysis of wind turbine air flow sensors.

Our Safety & Reliability team also has experience in Hazard Analysis and SIL assessment & verification that can support the safe operation of large scale infrastructure, from wind test facilities to biomass plants.
