Released CAESES 5.2 – The Turbomachinery Special

The new CAESES release 5.2 was developed with a strong focus on turbomachinery design and is dedicated to users with the CAESES add-on Turbo. It offers a wide selection of components, workflows, and methods to simplify and streamline the parametric modeling of turbomachinery geometries, while maintaining the high level of freedom and customization that CAESES is known for.

Streamlined Turbomachine Workflow

The new turbomachine workflow provides both an extensive selection of dedicated design components, and a step-by-step guide through the geometrical modeling process of a fully-parametric turbomachine design. After setting the machine (compressor, turbine, pump or fan) and the flow type (centrifugal/radial or axial), the workflow streamlines the creation of every necessary geometry object and parameter, to help you create a powerful and flexible parametric model in less than half an hour.

The wizard-like approach supports beginners and advanced turbomachine designers in selecting and using machine type dependent features available within the add-on Turbo, keeping the project structure clean and organized, and making the modeling process faster.

Take a look at the tutorial video below to start getting to know the new workflow and learn how to design a parametric centrifugal pump in less than 20 minutes.

Airfoil Blade

The new object type “Airfoil Blade” lets you create a fully-parametric blade based on an airfoil profile definition in a matter of minutes. It combines a 2D profile (feature) definition – either user-coded, or from a list of templates – with a 3D transformation to directly loft a surface in spanwise direction from hub to shroud.

Choose between

  • a cylinder transformation, which transforms the 2D profile onto a cylindrical surface,
  • ZRT (Z, Radius * Theta), which allows a transformation of a 2D profile onto a stream surface located between hub and shroud, where the x-coordinate corresponds to the z-position and the y-coordinate corresponds to the radius*theta value,
  • MRT (M, Radius * Theta) offers a transformation of a 2D profile onto a stream surface between hub and shroud, where the x-coordinate corresponds to the meridional m-position (streamwise arclength) and the y-coordinate corresponds to the radius*theta value.

Advanced Blade Fillets

A great amount of development time has been spent on blade fillet creation. The new fillet object allows you to easily create constant or variable radius fillets and offers the option to include a boundary edge optimization to let the fillet run up to any specified boundary curve.

A special thanks to our users who gave feedback and many great suggestions through our helpdesk and forum!

Calculate the Maximum Fillet Radius

A new feature calculates the maximum fillet radius between two blades, which guarantees a 100% robust and smooth fillet creation.

Use the maximum feasible fillet radius or set your own value to create a robust fillet with a constant radius around the blade geometry.

Variable Blade Fillet with Radius Distribution

Define flexible radius functions to design the blade fillet with variable radius from the leading edge to the trailing edge for both sides of the blade.

Variable Blade Fillet with Boundary Optimization

Optimize the fillet radius to run up to a pre-defined boundary to avoid overlap.

Analysis Tools for Blades

Quickly analyze any imported or existing blade geometry with the newly implemented analysis tools. You can now easily extract the mean camber surface, determine the blade and wrap angle (beta/theta) distributions, calculate the throat area between blades, or transform the 3D edges to the meridional plane. This toolkit allows you to quickly build a fully-parametric model from imported geometries.

New Turbomachinery Samples

New sample models for

  • a centrifugal pump,
  • a radial turbine with variable radius fillets and scallops,
  • a centrifugal compressor including splitter blades,
  • an axial fan,
  • and an axial compressor stator with endwall contouring.
