## **What's inside?**

This paper presents a **design process coupling a 3D inverse design approach** with a Multi Objective Genetic Algorithm (MOGA) for **axial cooling fan**. The aim is to reduce the leakage loss and profile losses to improve performance. The inverse design method parameterizes the 3D shape of the axial fan with a **reduced number of design parameters allowing a larger exploration of the design space** in the optimization process.

 

> Two designs from the optimization are analyzed in detailed by using 3D Computational Fluid Dynamic (CFD) calculations, which confirm that **the design optimized for minimizing leakage losses meets the design specification**. Detailed CFD also confirms the reduction in leakage losses in this design.

### In this publication, you will:

1. **Understand **the presented methodology multi-objective design of fans in which the blade shape is parameterized in terms of blade loading parameters used as input to a 3D inverse design code.
2. **Learn** how the 3D Inverse Design method is applied, with TURBOdesign1, to parametrically describe the blade geometry.
3. **See **the advantage of using a three-dimensional based approach in this project, it can be used to rapidly and automatically explore a large part of the design space to create impeller that meet contrasting requirements relating to efficiency, flow phenomenon, losses, manufacturing limitations, mechanical constraints or cost.
