Para­met­ric Impeller Design

The blade design capa­bil­i­ties of CAESES® have been com­pletely reviewed with version 4.0, and a lot of great features have been added for the design and opti­miza­tion of rotating machin­ery (pumps, tur­bocharg­ers, turbines etc.). CAESES® is able to create any type of blade (radial, axial, mixed), and any type of 2D profile def­i­n­i­tion can be mapped into a smart para­met­ric descrip­tion. This means that CAESES® is not a black box tool that is limited to a specific blade model — of course, not! With CAESES® — plus your company-specific know-how and expe­ri­ence — every­thing is in place to develop the best blade designs in the market!

Merid­ional Hub and Shroud

Use all the dif­fer­ent curve types in CAESES® to design your hub and shroud contours. Create smooth and variable shapes with our set of spe­cial­ized curve types.

Leading and Trailing Edge

Design 2D guides for leading edge and trailing edge in a smarter para­met­ric way. Reduce degrees of freedom — and hence the number of vari­ables — while still main­tain­ing most impor­tant blade characteristics. 

Mean Camber

Use the powerful script­ing envi­ron­ment of CAESES® to fully cus­tomize your mean camber def­i­n­i­tion. Choose between (m’,beta) and (m’,theta) mapping for your camber. BTW: Don’t worry, these script­ing sequences can also be auto­mat­i­cally gen­er­ated for you in case your are a bit nervous when reading the term ​“script­ing” … but once you’ve under­stood it, it’s really fun — trust us! 

Radial Func­tions

Don’t modify each blade section sep­a­rately, this is a tedious and time-con­sum­ing process. Instead, set up radial function graphs for all the 2D para­me­ters of your profile, to intu­itively control your mean camber char­ac­ter­is­tics in radial sweeping direc­tion. Use any curve type or math­e­mat­i­cal def­i­n­i­tion for such a function graph — with this design concept, lit­er­ally every­thing is possible, and it saves so much time! 

Thick­ness Definition

The same counts for thick­ness: Fully cus­tomize your 2D thick­ness curve only once, and then control it intu­itively for the entire 3D blade shape using function graphs. Define circular and ellipse-shaped leading edges, or any other mixed flavor of it … it’s up to you! 

Sim­u­la­tion-Ready

Impor­tant for ana­lyz­ing the blade shape with CFD: Receive sim­u­la­tion-ready geome­tries of your blade model, where con­ve­nient Boolean oper­a­tions generate clean and water­tight data for you! 

Fillet Modeling

CAESES® also offers you standard CAD func­tion­al­ity such as fillet modeling so as to quickly finalize your product designs. Now you are fully equipped with every­thing you need for high-end blade design! 

Automa­tion

With a single click, you can create a manual design can­di­date of your blade model that is managed next to your baseline design. Even better, let CAESES® do the job for you and automate the design creation process. In this last step, you can also plug-in your sim­u­la­tion tool, to cal­cu­late the per­for­mance of each design auto­mat­i­cally (while you are enjoying some drinks on the weekend ;-) …).
