What's inside?
This paper introduces a method to optimize propeller fans using a three-dimensional inverse design technique. The process involves enhancing the performance of a previously developed propeller fan through variations in vortex distribution, blade surface pressure loading and stacking during optimization.
By using the inverse design calculation, 3D blade shapes are derived with minimal input parameters to explore a wide design space, making it advantageous for design of experiments (DOE) analysis.
The objective is to enhance the fan's aerodynamic performance while controlling noise levels. A multi-objective optimization approach is utilized to strike a balance between different goals, resulting in an optimal design chosen from the optimization process.
In this publication, you will:
- See how by carefully controlling the flow physics in the fan passage and by using the 3D flow field predicted by the inverse design method, the aerodynamic performance has been improved considerably.
- Discover how you can explore a large design space with complex vortex and stacking distribution.
- Learn how hundreds of inverse design solutions can be investigated withing a couple of hours using a single core.
