On Design of Transonic Fan Rotors by 3D Inverse Design Method

Written by Peixin Hu and Prof. Mehrdad Zangeneh, Advanced Design Technology.

What's inside?

The application of 3D inverse design to transonic fans can offer designers many advantages in terms of reduction in design time and providing a more direct means of using the insight obtained into flow physics from CFD computations directly in the design process.

In this paper the further enhancement of the 3D viscous transonic inverse design code TURBOdesign-2 and its application to the re-design of NASA37 and NASA67 rotors will be described.

On Design of Transonic Fan Rotors Cover

In this publication, you will:

  1. Discover the design technics with the 3D Inverse Design method to re-design of NASA37 and NASA67 rotors. Two well known examples of NASA 67 and NASA 37 rotors are used to provide a step-by-step guide to the application of the method to the design of transonic fan rotors.
  2. See how to improve the overall quality of the designs, with 1.26% and 1.57% improvement of the efficiency.
  3. Understand why such an approach leads to a substantial reduction of the computational cost compared to the direct method.
