ducted fan setup. help me!

kr2552 · May 9, 2013, 04:10

First of all i am sorry that i'm not good at english

i made two geometry (stator, rotor) then i used turbo grid and made meshes

in cfx setup i use frozen rotor and ratio 1

but in result looks like discconection between rotor and stator

i check it by stream line

in rotor stream line moving rotational direction but in stator in just go down not affected by rotor

how can i solve it....... can u explain easily? i tried to read tutorial but i can not find proper example

Did you well defined connection constraint before meshing the domains? Take a look at that you need a connection mesh sizing

Can you post an image or what you are seeing?

Also, are you drawing streamlines using Velocity or Velocity in Stationary Frame?
