Commercial and Industrial Fans

Predict Performance and Optimize Fan Designs

SimScale is a 100% cloud-based CAE software for commercial and industrial fans that lets you test, validate, and optimize your designs through CFD, FEA and thermal analysis.



High efficiency is an important criteria in the fan design process as fans consume 18% of electricity in commercial and industrial buildings and processes. With standards such as ASHRAE 90.1-2013 and Commission Regulation (EU) No 327/2011, there are requirements for fan efficiency based on metrics like FEG, FMEG and FEI. These standards greatly impact fan design conditions and thus the selection by customers.
To meet efficiency goals, the classical approach of Design – Build – Test – Redesign is time-consuming and expensive. Commercial and industrial fans designers are now turning to an effective method to virtually test, make accurate aerodynamic assessment and optimize using engineering simulation. Computational Fluid Dynamics (CFD) is the method that is used for the computerized calculation of fan aerodynamic quality to accurately predict fan performance earlier in the design stage, analyze various designs, reduce the number of physical prototypes and expensive testing, optimize designs for maximum performance, and shorten design cycle and cost.

Flow Rates and Velocity

Flow Rates and Velocity

CFD enables you to predict the 3D flow field distribution for your fan design and determine the output velocities and flow rates for different operating conditions.

Static and Total Pressure

Static and Total Pressure

Analyze existing designs to determine the static and total pressure rise of the fan. Optimize current fan and blade designs to improve their performance.

Acting Forces and Moments

Acting Forces and Moments

Calculate the aerodynamic forces and moments acting on the rotor to determine the torque for various flow rates and RPMs.

Subscriptions and access to engineering simulation for every budget

Fan Efficiency

Fan Efficiency

Evaluate the static and total fan efficiency for an existing design at different flow rates to determine the peak operating condition. Analyze the designs and based on the results, make improvements for increasing efficiency and costs saving.

Fan Performance

Fan Performance

Investigate fan designs and determine their performance in terms of static and total pressure rise for a range of operating flow rates. The performance curves obtained are key indicators for deciding whether the design meets the requirements or needs optimization.

Rotor Torque

Rotor Torque

Determine the net torque on the rotor due to aerodynamic forces for a range of operating revolutions per minute (RPMs).

Case Study - Cross Flow Fan

Case Study - Cross Flow Fan

Testing Vibration and Aerodynamics with CFD

Producing an even laminar airflow and allowing horizontal or vertical mounting, a cross flow fan prevents the overheating of electronic components. Early in the design process, fans can be virtually tested with CFD to make sure the highest efficiency and performance and the lowest noise are achieved. A simulation software can also help in performing vibration analyses and predicting the aerodynamics of the fan, everything long before creating a physical prototype.

CFD Analysis for Predicting Aerodynamics

When selecting fans for HVAC applications, many engineers choose centrifugal fans for their energy efficiency, durability and ease of maintenance. SimScale’s CFD solution allows designers of centrifugal fans to accurately calculate flow rates, static pressure, total pressure, static efficiency, total efficiency, peak total efficiency, forces and moments acting on the fans, and more.

Simulation based Fan design

Simulation-based design of complex geometries

Fans need to fulfill very strict governmental regulations which is why it is crucial that they are designed to be as effective as possible. Bringing the design faster to the market is also important to stay ahead of the competition. You can achieve this with the simulation techniques you learn here!

I loved the fact that I could do what I need to do in a browser. I started working without installing any software. Using any computer I could upload the model and start the analysis. That was the big “wow” moment.
