Designing Optimal Fans Using TURBOdesign1 at Ebm-Papst

Ebm-Papst produces  high-quality  fans  and  motors  for many  markets  such  as  heating  and  air-conditioning,  ventilation,  refrigeration, automotive, IT/telecom and drive technology.

Design Process
The direct approach for designing a new impeller requires a lot of geometrical parameters. In addition, the correlation between geometrical parameters and aerodynamics is unknown in most cases. Therefore, a lot of CFD calculations or measurements have to be done until the best configuration is reached.

Advantage of TURBOdesign1
Searching for new tools to make the design process faster and more efficient, an extensive  benchmark of  available design  tools was  carried out  at  Ebm-
Papst. TURBOdesign1 shaped out to be the most suitable tool for developing new fan blades,  the promising  gain of time and a better understanding of the aerodynamics.

Conclusion
TURBOdesign1 can be a valuable tool in designing fans. It’s geometrical parameters are reasonable in realising the usual design specifications, with  blade  loading  being  an  important  parameter  for  aerodynamic and aeroacoustic optimisation.
