M4 Generic Method for Meridional Geometry Parameterization

The version 6.4 update to TURBOdesign Suite provides significant new features and functionality to enable designers to produce highly optimised designs faster than ever before. One new functionality is outlined below:

In TURBOdesign1 - A  new flexible parameterization approach has been developed and integrated in the existing Meridional Geometry Generator, which allows creation of arbitrary meridional geometries. The user can specify a number of sections and for each location define the width, orientation and location of the reference points used for rotation. For example, this meridional geometry parameterization can be used when optimizing mixed flow pumps and centrifugal compressors with return channels by making use of a small number of parameters (Figure 1).

The implementation of this new meridional geometry method has been done in such a way as to make it fully available to TURBOdesign Optima and to TURBOdesign WB. This means that the M4 parameters controlling the meridional geometry will now be available within ANSYS Workbench when setting up a case with TURBOdesignWB.

Thickness Distribution Window With Streamwise and Spanwise Control

A new thickness distribution window has been developed to give more flexibility when defining the thickness distribution through equations. Another new feature introduced is the spanwise control which is defined graphically in the same thickness window via Bezier or Cubic splines (Figure 2).
