Computational Performance Prediction of Fans Based on Multiple Variable Parameters

Apstrakt

This technical specification provides guidance on the use of Computational Fluid Dynamics for the steady-state prediction of fan performance at defined operating points. These operating points include those relating to simulated acceptance tests (EN ISO 5801:2017 for axial fans, EN ISO 13350:2015 for jet fans), as well as modelled in-situ performance (EN ISO 5802:2008/A1:2015 for axial fans).
The objective of this guidance is to enable practitioners to follow a robust methodology to ensure that their predictions of fan aerodynamic data (including volumetric flowrate, pressure rise and absorbed power) lie within one of the tolerance grades defined in ISO 13348:2007.
