Acoustic Evaluation of Forward and Backward Swept Axial Fan Design for Automotive Applications with Identical Aerodynamic Performance

Written by Anand Sivaram Sivaramakrishnan, Dr. Mihai Bleiziffer and Felix Girmscheid from Hanon Systems, Deutschland GmbH.

What's inside?

This paper introduces an innovative approach to address a significant research gap in axial fan design for automotive applications. 

The collaboration between Hanon Systems and Advanced Design Technology Ltd. (ADT) utilized advanced design techniques and the inverse design methodology to develop axial fans with the same aerodynamic performance while minimizing acoustic emissions. 

Acoustic-Evaluations


The main focus was on comparing the acoustic behaviour of forward and backward blade designs in a unique context. The methodology involved applying advanced turbomachinery design methods and inverse design principles to create fans with identical airflow performance and superior acoustic characteristics, all while maintaining the same blade dimensions.

In this publication, you will:

  1. Discover a methodology encompassing the application of advanced turbomachinery design methods and inverse design principles.
  2. See how this enables the design of axial fans with identical aerodynamic performance characteristics irrespective of blade sweep.
  3. Learn valuable insights into the acoustic aspects of axial fans, particularly in the context of automotive applications.
