# Design of a Box Fan Rotor using 3D Inverse Design Method

Written by Hidenobu OKAMOTO, Hiryoshi WATANABE (Ebara Research Co., Ltd.), Mehrdad ZANGENEH (University College London) and Akira GOTO (Advanced Design Technology Ltd.)

## **What's inside?**

In this paper, a 3D inverse design code TURBOdesign1 is applied in a parametric way to the **design of the blade geometry of an axial box fan**. The inverse design method designs the blade for a specified distribution of blade loading and spanwise circulation (or specific work) distribution. By changing the blade loading and spanwise circulation distribution, 4 different fan designs are created. The flow through these fans are computed by using a 3D CFD code and **compared to that of a conventional design**.

> The results of the CFD computations indicate that a reduction in blade loading at the leading edge of the fan can **lead to noticeable change in performance characteristics** as well as the strengh of tip leakage vortex which may results in a reduction in fan noise.

### In this publication, you will:

1. **Discover **the design technics to get a noticeable change in performance characteristics as well as the strengh of tip leakage vortex which may results in a reduction in fan noise.
2. **See **how to specify an appropriate distribution of blade loading and spanwise circulation and distribution.
3. **Understand** the advantage of using TURBOdesign Suite and the 3D Inverse Design method in this project.
