       At first ,this is my model

fan.png

  

     And this is my domain (for AMCA 2100-99 text)

domain.pngdomain2.png

 

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

And then

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

 

Result.png

 

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........

But I see the Cut plots52.png

 

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....
