Why choose a simulation- and data-driven design approach?

Accelerated design space exploration

Simulation-driven design enables engineers to evaluate thousands of blade geometries and operating conditions virtually, identifying high-performing concepts much faster than traditional sequential design processes. This shortens development cycles while expanding the range of design alternatives that can be explored.

Higher aerodynamic efficiency and performance

Simulation-based optimization helps refine blade geometries to achieve objectives such as increased efficiency, higher pressure ratio, reduced losses, and improved flow uniformity. The result is turbomachinery that delivers better performance while meeting demanding design constraints.

Better understanding of complex flow physics

Large simulation datasets provide detailed insight into phenomena such as flow separation, secondary flows, tip leakage, and shock interactions. These insights enable engineers to make more informed design decisions and develop more robust, high-performance blade designs.

CAESES’ blade design capabilities

CAESES is a specialized CAD and automation tool for optimizing complex, performance-critical geometries, with dedicated capabilities that make it particularly suited for the design of cutting-edge bladed turbomachinery components.

Blade Design Types

Smart parametric modeling

Complete parametric blade modeling capabilities for radial, axial, and mixed flow rotors and stators.

Control of the blade shape via discrete parametric cross sections, continuous control via radial parameter distribution functions, or customized modeling approaches, e.g., for radially fibered or flank milled blades.

Blade Design Airfoil

Axial machines

Angle and shape preserving transformations for axial machine airfoil modeling.

Blade Design Functions

Radial machines

Flexible control of blade, wrap angle and thickness distributions for radial impellers.

Blade Design Workflow

Intuitive yet customizable

Dedicated modeling workflows for turbomachinery greatly simplify the process.

Yet, high level of customization, i.e., no black box models and full freedom to set up user-defined parameterizations and workflows.

Blade Design Variation

Robust variation

High robustness and flexibility of parametric models for reliable automated design studies and optimization.

Blade Design Details

Detail oriented

Comprehensive tuning possibilities of shape details like root fillets, scalloping, leading edges, and blade tips.

Blade Design Flank Milling

Constraint handling

Full consideration and integration of manufacturing constraints (e.g., flank milling, casting, additive manufacturing).

Blade Design ANSYS

Flexible interfacing

Import and processing of geometry data from external preliminary design tools and special export formats for turbomachinery like geomTurbo or Turbogrid.

Direct integration in ANSYS Workbench through CAESES Workbench apps.

What our customers say

Nico Lachenmaier

“By using CAESES, we could mas­sively bring down our turbine design cycle from several months to only a few weeks.”

Tilman auf dem Kampe

“We launched a pilot project with FRIEND­SHIP SYSTEMS to evaluate CAESES in May, it helped us solve a time-critical task in July and it became a design tool by October.
By then, we had created flexible and robust para­met­ric models for complex parts, enabling us to optimize in design spaces we had pre­vi­ously not been able to explore.”

“I enjoy using CAESES, as it allows me to para­met­ri­cally generate geome­tries without ever going through a CAD design cycle.
In this sense, it really stream­lined my process from concept to CFD verification.”

“I have suc­cess­fully been using CAESES for many years now. It allows me to create my own cus­tomized toolbox with every­thing I need in the dif­fer­ent stages of the pump design process.
The func­tion­al­ity of CAESES greatly accel­er­ated and com­ple­mented our tra­di­tional design process. Finally, it lets us improve the quality of our various types of pumps.”
