Hi - we are NUMECA!

CFD and CAS Software

… this is what we do! We are highly specialized in all questions concerning computational fluid dynamics (CFD), acoustic simulations (CAA) as well as optimisation and meshing solutions.


At our site in Altdorf, we offer advice and support to both our well-known customers and those who are yet to become one. Our consulting service is clearly defined: you benefit from our expertise in the CFD and CAA segment, e.g. in the field of turbomachines and their optimisation.


We provide assistance for your simulation projects and develop precise solutions tailored to your needs. Would you like to know how? Please feel free to look around and find out for yourself!

Supercritical CO2 Compressor Simulation - From Design to Optimisation

Supercritical CO2 Compressor Simulation - From Design to Optimisation

Supercritical carbon dioxide (sCO2) Brayton cycles are emerging as an alternative to steam Rankine cycles. Designing a turbomachinery for sCO2 can be challenging because of extreme heat ratio variations and low compressibility of the gas. In this webinar, learn how to simulate a sCO2 compressor, from design to optimisation, efficiently and accurately.
