ADVANCED DESIGN OF TURBOMACHINERY BLADES CAESES® is a powerful and flexible platform for the design of turbomachinery blades, including the optimization of advanced features such as endwall contouring.

All parametric blade models can be robustly linked to any meshing and simulation tools to run automated design studies and optimizations with CFD. BladeCAD is a geometrical design tool of turbomachinery bladings, which was developed under NASA supervision and has incorporated a new methodology of the way that bladings should be designed.

According to this approach, blade cross-sections are initially defined and are then lofted in order to provide the corresponding 3D by:   Thanks for the interest. I think large parts could be implemented as macros of existing functionalities. When it comes to the blade design, my code is largely based on the algorithms of Casey, A Computational Geometry for Blades and Internal Flow Channels of Centrifugal Compressorsand Miller, BladeCAD An Interactive Geometric Design Tool for turbomachinery blades, (NASA Report).

Published: (). This book outlines in detail geometric models of single-point and multi-point cutting tools and proposes a set of new three-dimensional (3D) standards for defining the tool geometry.

The 3D geometric models of cutting tools would help the design, analysis and manufacturing processes of the cutting : $ Currently, 3D-CFD design optimization of centrifugal compressors in terms of the surge margin is one major unresolved issue. On that account, this paper introduces a new kind of objective function.

The objective function is based on local flow parameters present at the design point of the centrifugal compressor. A centrifugal compressor with a vaned diffuser is considered to demonstrate the Author: Johannes Ratz, Sebastian Leichtfuß, Maximilian Beck, Heinz-Peter Schiffer, Friedrich Fröhlig.

This paper presents a gradient-based design optimization of a turbocharger radial turbine for automotive applications.

The aim is to improve both the total-to-static efficiency and the moment of inertia of the turbine wheel. The search for the optimal designs is accomplished by a high-fidelity adjoint-based optimization framework using a fast sequential quadratic programming by: 1.

shape-optimization of turbomachinery blades applicable to general cases has not been developed yet. This study aims to create a mechanism whose nal purpose is to provide an easy way to build high-performing blade shapes both in the early steps of the design of new turbomachinery models and in the improvement of current con gurations.
