Custom made fan and turbine design

Fans and turbines are available in countless standard types and sizes, yet many applications demand a truly tailor-made solution. At Actiflow, we specialize in the aerodynamic design and optimization of both axial and centrifugal fans, as well as wind turbine blades ranging from 1 to 100 meters in length for both horizontal and vertical axis turbines.

We do more than digital design alone: Actiflow offers prototype manufacturing support, experimental testing, and continued involvement throughout the development process. This ensures the final product meets performance targets and fully aligns with our client’s expectations.

Our clients

Our clients operate across a wide variety of industries, including indoor ventilation, wind energy, street cleaning, and firefighting systems. Over the years, we have supported:

Companies requiring a fan or turbine with specific performance characteristics or dimensions
Organizations for whom fans or turbines are new products within their portfolio
Clients without in-house aerodynamic expertise
Businesses that choose to outsource complete development projects due to time or capacity constraints

The specific industry is often secondary. If you can define your boundary conditions and design objectives, we can assess feasibility and develop a fan or turbine solution that meets your requirements.

Our services

We provide aerodynamic design and optimization services for a wide range of fans and turbines, combining advanced simulation techniques with experimental validation.

Fans

At Actiflow, we design both axial and centrifugal fans, using simplified calculation models, panel methods and high-end 3D CFD simulations.

For axial fans, our focus is on the aerodynamic shaping and optimization of rotor blades for the intended operating conditions. In centrifugal fan design, we also consider the housing geometry and blade–housing interaction, as these strongly influence performance, efficiency, and noise.

By visualizing airflow patterns, pressure distributions, and losses, we continuously refine the design. Whenever possible, prototype measurements are performed to validate the simulations. Noise and vibration reduction are typically addressed through a combined approach of numerical analysis and experimental testing.

Turbines

Actiflow has extensive expertise in the aerodynamic design of wind turbine blades, from small wind turbines for decentralized energy production to large multi-megawatt machines with blades of 100 meters long. Both classic horizontal axis turbines and vertical axis turbines are part of our portfolio.

Our portfolio includes both horizontal-axis wind turbines (HAWT) and vertical-axis wind turbines (VAWT). Designs are developed using a combination of simplified calculation methods and advanced 3D CFD simulations. Once the aerodynamic design is finalized, we can test scaled prototypes in a wind tunnel to verify performance.

If desired, we remain involved throughout all stages of product development, ensuring a smooth transition from concept to final, validated product.
