Simulation- and data-driven volute design
Explore and optimize volute geometries through parametric geometry variation, automated simulation workflows, and multidisciplinary design studies.
Why choose a simulation- and data-driven design approach?
Accelerated exploration of design alternatives
Simulation-driven design enables engineers to evaluate a wide range of volute geometries virtually, rapidly identifying configurations that best meet performance objectives. This significantly reduces development time while enabling a more comprehensive exploration of the design space.
Improved flow distribution and overall performance
Simulation-based optimization helps refine the volute geometry to achieve more uniform flow distribution, lower pressure losses, and better matching with the impeller or diffuser. The result is higher aerodynamic efficiency and improved overall turbomachinery performance.
Deeper insight into complex internal flow behavior
High-fidelity simulations reveal flow features such as separation, recirculation, secondary flows, and regions of high loss within the volute. These insights enable engineers to make informed design decisions and develop more efficient and robust flow passages.

FAQs
Why is volute optimization important for turbomachinery?
The volute strongly influences flow uniformity, pressure recovery, and the overall efficiency of centrifugal compressors and pumps. Optimizing its geometry can significantly improve machine performance and operating stability.
How does CAESES automate volute design?
CAESES creates fully parametric volute models that can be coupled with CFD simulations and optimization algorithms. Automated workflows evaluate numerous design alternatives to identify volute geometries that achieve the desired aerodynamic or hydraulic performance.
