Running a simple hydropower flow simulation with the use of an actuator disk

EJohn · January 16, 2019, 13:44

Hello OpenFoamers,

I want to model a small flow channel with a water turbine midway that does not have any impellers for reduced complexity. At the impeller location I want to have some sort of actuator disk in the domain where I can set the hydraulic power loss across the impeller to represent a pressure loss.

Please let me know how I should approach this problem.

Thanks,
John

I also have a similar problem but couldn't find any info regarding power coefficients.

Sorry for being persistent but can anyone provide suggestions on where I can start.

Thank You in advance,
John
