At first ,this is my model
And this is my domain (for AMCA 2100-99 text)
And this is my seting ,i want to find the P-Q curve
B.C rotational zone
fan (stator),you can see ,i choose the fan,and set the filiter Faces
choose "Romove out of domain faces","Romove outer face" ,"Keep outer and fulid-contacting faces">>Reall wall (stator)
you can see the fiuge
choose "Romove out of domain faces","Romove outer face" ,"Keep outer and fulid-contacting faces">>Reall wall (no stator)
And this is my Mesh
And this is my Result
There is a big problems,
|SG Volume Flow Rate inler is -0.0397cmm|
|SG Volume Flow Rate outlet ture is 0.040cmm|
I know the positive and negative is represent the direction,I check all of the teach video,the negative is represent the flow is out......
So my result, it maybe wrong........
the velocity is out of the outlet ture.......
Could you tell me why?And it's wrong,or somthing unreasonable, please tell me why.......
I have experiment for text this fan,the simulation's result it have a lot of Error for ture ,could you give me some suggest? Thanks....
