Wind & Hydrokinetic Turbines

Optimized Turbine Designs Improve Power and Reduce Costs

Doyle CFD provides high resolution simulation data and optimized designs for wind and hydrokinetic turbines to improve power, reduce material costs, and rapidly iterate through design paths to find an optimal design. Our analysis is driven by data from state-of-the-art Computational Fluid Dynamic (CFD) and Finite Element Analysis (FEA) simulations.  Using CFD we are able to accurately analyze designs without the need for developing prototype models for each design in question. By coupling CFD with our in-house engineering workstations and cloud computing, we are able to offer clients the ability to analyze far more designs on a constrained budget. Once optimal power configurations are honed in, we can couple the fluid dynamic forces from CFD into our FEA software to determine whether components are strong enough. Furthermore, we use our in-house laminate program to develop appropriate composite lay-ups for blade designs. Past projects range from a surface piercing oscillating hydrokinetic turbine, the high altitude Altaeros turbine, optimization of VAWTs, a large scale hydrokinetic turbine for deployment in the Gulf Stream, and the V-Squared turbine that uses a duct to accelerate the flow around the rotor. 

 

Fluid Dynamics

Our turbulent flow RANS CFD technology can be used to produce accurate results similar to wind tunnel, flume, or full scale prototype testing without the need to build expensive models. We frequently use RANS CFD to optimize turbine blade profile shape, twist, chord and other parameters to deliver the best design possible to clients. Using this technology we can help clients optimize designs for their niche market and turbine type. Once worthy designs are  created, we frequently test prototypes with clients before entering further design phases or production.

 

 

FEA & Laminate Design

We can analyze and help design the overall structure of a turbine, mast, shroud, blades, or any other turbine component. Using CFD, we can obtain pressure and inertial loads acting on turbine blades. Coupling those results with our FEA analysis, we are able to determine stress and deformation of the blades at different loading conditions. These results allow you to minimize weight and material cost, while maintaining proper factors of safety. We have developed an in-house laminate calculation program to determine properties of laminate schedules by mathematically combining plies or fabrics layers of varying properties. Combining accurate laminate lay-up properties with FEA allows us to accurately model and optimize laminate structures.

 

 

Prototype Design & Testing

Prototype testing is an important part of the design cycle even when utilizing CFD for design work.  We have experience designing, building, instrumenting and testing a wide range of kinetic turbine prototypes.  We've tested turbines in real world conditions, in hydrodynamic flumes and wind tunnels.  We are experts at interfacing sensors systems and data collection devices.  We work with a number of local machine shops and laminate fabricators to produce any needed turbine prototype component.      

Animation

We know how to bring designs to life with breath taking animation and rendering capability.  The same 3D models and high performance computing we use for CFD work can also be used to create physically realistic animations that can be used for promotional or education purposes.  We have experience animating everything from under water hydrokinetic turbines to vertical axis wind turbines.  We know how to work with designers, artists and other interested parties to create animations that tell your story.
