A request for OpenFOAM case files of VolturnUS-S platform #136

Closed hachikoi1 closed 1 year ago

Description of feature

Dear Developers Could you please provide the OpenFOAM case files of UMaine VolturnUS-S platform?

Very thankful Best regards,

Potential solution

Can you think of ways to implement this?

We do not currently support OpenFOAM analysis of the reference turbine. If you would like WAMIT input files, please see: https://github.com/IEAWindTask37/IEA-15-240-RWT/tree/master/OpenFAST/IEA-15-240-RWT-UMaineSemi/HydroData

Dear gbarter I found some analysis of UMaineSemi platform in https://www.nrel.gov/docs/fy20osti/76773.pdf using OpenFOAM. Do you have any OpenFOAM cases of the platform? Best regards,

Unfortunately that was a one-off activity and those analysis files are no longer available

Dear gbarter I want to calculate the quadratic drag at platform COG. Could you please provide the drag coefficient Cd for each platform structure and provide the formula for calculating quadratic drag (especially in the Roll, Pitch and Yaw direction)?

gbarter commented 1 year ago

That info is also not readily available, sorry. You would have to do some analysis to compute the values you are looking for.

hachikoi1 commented 1 year ago

That is ok. Thank you very much for your reply

I am very sorry to bother you again. I performed a decay test with an initial pitch angle of 5 degree based on the IEA-15-240-RWT-UMaineSemi tutorial, but my results seem to be wrong. The rotational displacement is ultimately non-zero. I ensure that the coordinates of COG and COB are set correctly. Could you give me some advice?

Best regards,
