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. SimScale’s CFD solution allows industrial fan designers to calculate flow rates, static pressure, total pressure, static efficiency, total efficiency, peak total efficiency, forces and moments acting on the fans and more. In addition, it also enables them to analyze and optimize fan vibrations and conduct structural analyses on the foils, brackets, and structural mounts to ensure structural reliability.

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

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

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

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

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

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



Centrifugal Fan – CFD Analysis

CFD Analysis of Centrifugal Fan to Predict its Aerodynamic Efficiency

This simulation was performed on a centrifugal radial compact fan with forward curved impeller that is used for electronics cooling applications such as thermal management for infotainment, IT and telecom systems. Its purpose was to predict the fan's aerodynamic performance and identify areas for design optimization.

Tangential Fan – Aerodynamics and Vibration Analysis

Tangential Fan Study of Aerodynamics and Vibration Performance

Tangential fans are widely used throughout the HVAC and electronics industries; they produce a fairly two-dimension flow, and can be mounted horizontally or vertically. The design objective is to obtain maximum flow across the fan, while maintaining lowest possible levels of vibration by finding the maximum displacements expected.

Christopher Quijano

I have used a lot of simulation packages over the past 25 years, including Nastran, Ansys, SolidWorks, and a whole host of others. I have been using SimScale for about nine months now and it has become my goto simulation tool. It allows me to run models larger than I have ever conceived on my own workstation.
