    I need for help for simulation a centrifuge fan

    Jack Gu

             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

       

      set inlet.pngrotational.png

      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

      outg.png

       

      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....
