Hello, We are working in AWE (Airborne Wind Energy) systems CFD modeling. To this purpose, we are computing the aerodynamic forces on a KITE power system model. We are already controlling the rotations velocities and angular displacements with the turbomachinery model. The rotations and the angular ...

Hello Yvan, It seems like when we have copied the codes to the forum, the braces didn't copy at all.. Although there was an error in the for loop (1<3 :oops: ) and we have found another silly bug in another subroutine. Everything is working perfect now. We have attached a gif where it can be seen th...

Hello Yvan, Thank you for your help and your quick answer. We have some setbacks given that the function "cs_turbomachinery_set_rotation_velocity" is implemented in the version 5.3 of Code Saturne, and we were working with the 5.0 version. Therefore, we had to install that version in our H...

Hello, I'm trying to model the aerodynamics of an object in a three-dimensional domain. The main idea is to simulate the fluid-dynamics around the object while it's moving with a prescribed time-dependent angular displacement. To accomplish this, my idea is to use the Turbo-machinery model, which I'...

Thanks for your help Erwan. Here I send you the square case that i've runned in Code Saturne version 5.0. I've tried both, laminar and turbulent regimes without success. From the user subroutines you will see that I'm rising up the thermal conductivity of the fluid domain to 720, this is in order to...

Hello Yvan and Erwan, I've done the internal coupling between the vane and air, coupling the field "total_energy" because of the compressible module. Code saturne seems to run without any problems(see figure "temp_vel.png"), but I think I'm doing something wrong with the coupling...

Yvan and Erwan, I've tried imposing the heat flux on the vane surface using user subroutines and worked like a charm!. It was just missing from the GUI. Now I'll try to do the internal coupling, I'll let you know how the coupling turns out with the compressible module. I'll have in mind your recomme...

Hello, I'm working on a gas turbine blade simulation. Air velocities are rounding Mach 1, therefore I'm using the compressible module of code saturne. The idea is to solve the hot gases around the airfoil using the compressible module, and do an internal coupling over the surface vane (Fluid-Solid i...
