confused
yes, i can measure the flow rate with a rpm set. but this is because i have the prototype. how can i predict the flow rate with another prototype?
if i want to change some geometry characteristics,...

i'm back...
hello guys...
i´m back studyng this problem:cool:. i don't understadn two points:
1 - i would be able to make a curve of rotor-shaft vs cfx torque & rpm. but i can't determine the pressure of the...

there is no problem to me at all because i have the data sheet of the motor, and i can measure the pressure loss (because i have a prototype of these rotor/stator)
but, if i had not this pieces to...

hi all...
i'm modeling a rotor-stator with a DC motor driven the rotor.
so i need to compare the torque in the rotor (tool--function calculator--torque) to the torque shaft to this RPM in the data...

calculating invalance
how can i determine the invalance?
the torque (tool--function calculator--torque) is the same of the net torque? (shaft - vs - load)
i'm not sure about this point..

So It stem's that I was wrong!
Suppose I wan to know if a designed geometry can reach a desired flow rate.
So I run one set up with this (desired) flow rate, and a proposed rpm, then using the imbalance of torque I will know...

question
glenn, i have a new doubt.
when i set the convergence criteria i can set the invalance to zero, so i could obtain zero torque of imbalance in each run, so: how do i know if the boundary conditions...

very interesting!!
mehrdadeng , ghorrocks i think you have an answer for my questions!
i have trying to do this! i'm investigating a hairdryer fan. i want to optimize the geometry and i need to specify a motor (torque...
