Hello everybody!
I am thinking about making a master degree in CFD. I am very beginner in both CFD and fluid dynamics subjects. However I am very interested in learning fluid mechanics and work in future for wind engineering companies. I want to simulate wind turbine and optimize its geometry (especially blades geometry) to given wind speed (it could be constant for this purpose, for example V = 6,5 m/s). So I have two steps: 1. simulation and 2. optimization. I want to try analyze 500kW HAWT turbine. We have ANSYS Fluent at our university, however I am thinking about OpenFoam which is free, so I could use it also at home. Maybe I will do it in Fluent, but for now I would like to focus on OpenFoam. I have made few "beginning steps": I have gone through some OF tutorials and have tried to build geometries in GMSH, Discretizer, HelyxOS and SALOME. I have few questions regarding wind turbine simulations in OpenFoam and such simulations at all (not focusing only on OpenFoam): 1. Of course I need strong physics background to do this. Presently my knowledge of fluid mechanics is very limited (as you see), but I want to change this in near future. What kind of flows should I learn? (suitable for my case) And what subjects should I mainly focus on? 2. There are many solvers in OpenFoam. Which should I get to know?. What OF tools should I also learn? I suppose I will need to know snappyHexMesh for meshing and pyFoam for optimization and working more efficient with OF. 3. Could you recommend any "best practices" resource about wind turbine analyzes (simulation/ optimization, etc.)? I would like to learn all steps I have to go through. Maybe there are some examples of such analyses in OF (or Ansys Fluent)? Thanks for advice and any help - I appreciate this! Regards, Robert PS. I want to add that: 1. My knowledge of C++ is very limited. I know only Python and C#. But I am willing to learn C++ if it is required or highly recommended. 2. Is it good to make such analyses in two apps (OF and Fluent) or should I better focus on one (I was thinking about using same geometry / mesh in both applications). 3. If you have anything you want to send me by e-mail instead of uploading here on forum, here is my e-mail: cad cae _ pl @ int eria . pl (please remove all spaces in address) |

Hello All,
I'm doing wind turbine analysis on phoenics and i'm a beginner user of phoenics. can any 1 out here send me a tutorial about how i can analyse a 3 blade Horizontal axis wind turbine and calculate power out of it? any help is appreciated. |
