negative efficiency of centrifugal pump
please help someone.
my simulation is converging without showing any reverse flow. but the result is
negative head generated
flow rate is ok.
Please help somebody..i am still sttuck.
please help somebody..
I tried every possibility..
time step factor ... and what not...
thanks from heart.. !!
Are you sure you have the rotation and torque vectors defined correctly? And the flow set up correctly? Have you manually calculated the rotor torque and rotation to check it makes sense?
