Modern Design of Automotive Axial Cooling Fans Using Inverse Methods

Written by M. Bleiziffer, A. Sivaramakrishnan and R. Schoele from Hannon Systems, Prof. M. Zangeneh from University College London and Dr. J. Zhang from Advanced Design Technology, Ltd.

What's inside?

This paper shows briefly the advances in the aerodynamic and acoustic developments for a new axial electronic cooling fan family by using inverse design. This is realized by using reverse engineering function of inverse design method to obtain blade loading of existing high-performing designs and then use this loading incorporating features used in current existing serial designs.

The reverse engineering process helps to capture the main know-how in the design of previous high-performing fans in terms of main inputs of inverse design method such as spanwise work, streamwise loading and stacking conditions.

Starting from these previous input specifications the inverse design method can be quickly used to optimize fans with new specifications in terms of diameter, flow rate, pressure rise or torque. It is also shown that the new fan design shows improved efficiency and improved acoustic.

In this publication, you will:

  1. Discover the methodology to create an optimum design from the existing blade;
  2. Understand how the 3D inverse design approach enables turbomachinery designers to rapidly develop an automotive axial cooling fan;
  3. See how to generate a new fan design with improved efficiency and improved acoustic.
