torque calculation of impulse turbine
I created a case by combining the interDyMFoam (tutorials/multiphase/interDyMFoam/ras/damBreakWithObstacle) and pimpleDyMFoam (tutorials/incompressible/pimpleDyMFoam/propeller) to achieve the simulation of impulse turbine (multiphases flow and AMI). The screenshot of velocity field is shown in attachment containing three nozzles and a runner.
And now, I want to calculate the efficiency. A great issue comes out HOW can i obtain the torque (pressure and viscocity torque ) of runner. I have no idea about this issue. Any advice will be appreciated.
Haven't got much of experience on this but… couldn't you just use a force calculation to computer the moment aruond the axis of rotation?
Now, I dont know how to report force in multiphase case. So i cant obtain torque without force. In singlephase case, the force/torque can be obtained by adding the following code in controlDict
