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.
