Hello friends,
Sorry to bother you. My CFD skills not good. I want to ask you a question about fluent-fan model. I am trying to model an air cooled steam condenser. I have to model a axial fan(pressure jump) in fluent but I dont know how I can do it. This is my model. While creating the geometry, should I draw the fan as a volume or a surface. thanks in advance. Have a nice days |

If you are interested in the flow structure and its effects on the performance, I would definitely go for a 3D Fan Model, with all the nitty gritty surfaces of blades, hub, and creation of rotating domain and use MRF.
But if I already had a fan curve, I would attach it to the 2D Circular surface, either a polynomial or as piecewise linear and then move ahead. On another note, I would definitely extend the domain on the fan side to be on the safer side. Hope this helps |

What you need to do is to make the fan surface to be a shared topology to make it work as a fan (Thats what I do in spaceclaim).
Wouldn't it be possible to generate a fan curve with the data available by using fan laws ? |

I am using design modeler, I made the fan surface as share topology I mean I used the share topology tool and its including all parts, but fan still not showing in boundary condition.
