Re: Rotor 37

Hello, Thank you very much for answering. At Yvan: Yes, indeed this case represents a transonic compressor with the following aerodynamic design parameters: • Number of blades: 36 • Tip diameter at leading edge: 0.5074 m • Hub diameter at leading edge: 0-3576 m • Rotational speed: 17188.7 rpm (1800 ...

Rotor 37

Hello, I am trying to run a simulation of NASA Rotor 37, using the frozen rotor model of Code_Saturne’s turbomachinery model. There is a picture attached to this post which shows a section of the whole geometry as the model for the numerical simulation. The geometry was meshed with approximately 1.6...

Re: Laval nozzle

Hello Yvan, Thank you for your feedback. Referring to the practical user’s guide I chose the two-scale model type of wall functions for the k-omega-SST model. I expected a logarithmic respectively linear modelling of the velocity field depending from the distance to the wall and the velocity to be n...

Re: Laval nozzle

Good morning Erwan, Thank you for replying. I changed my setup a little bit and attached the xml file to this post. I am wondering why I can’t see the no-slip condition at the wall. I chose the k-ω-SST turbulence model and the smooth wall boundary condition and expected the velocity at the wall to b...

Re: Laval nozzle

Hello Yvan, please, excuse me for delayed answering. Thanks to your help I got the simulation started and the results are quite promising. The problem was the time step input. Do you know if it is possible to contact the person who is involved in developing the compressible module? It would be nice ...

Re: Laval nozzle

Hello Yvan, thank you for your reply. It would be nice if you could help me with this issue. However, in case you couldn’t provide any help regarding this specific problem, you maybe can help me in a different way. Indeed I spent some time to get familiar with Code_Saturne since it is my task to exa...

Laval nozzle

Good morning and a happy new year, I am completely new to Code_Saturne and I am struggling with my first model. I am running Code-Saturne version 4.3.1 on a windows 7 operating system and so far, for the setup I have just used the GUI. I am trying to simulate a two-dimensional flow through a laval n...
