How to Model a Ducted Fan in Gambit?

AI Thread Summary
Steve is seeking guidance on modeling a ducted fan in Gambit for simulation in Fluent to optimize his design. He has created a model in Pro Engineer and exported it in IGS format but is struggling with the Boolean operation in Gambit, which leaves him with only one volume after subtracting the ducted fan from the surrounding box. He intends to use the sliding mesh technique and multiple reference frame method, noting the rotor's movement and the duct's stationary position. Additionally, he mentions a PhD dissertation related to duct design that could be useful for others in the field. The goal is to estimate the thrust of the ducted fan during hovering.

Hi, my name is Steve..

I am working on a ducted fan. I want to simulate it in Fluent in order to optimize my design. I know that sliding mesh technique and multiple reference frame method will be used but I am having problems in Gambit.

I do not know how to model it in Gambit. I have made my model in Pro Engineer and exported in IGS format. I made a box around the ducted fan and then subtracted the ducted fan (Duct + rotor) from the box using Boolean operation. But after subtracting it from Box only one volume is left.

Please can someone guide me how to handle the box and ducted fan (duct + rotor) in Gambit. Because rotor is moving and duct is stationary.

If you are doing duct design you should read my friends PhD dissertation.

Yes I am designing the duct. I want to estimate the thrust of ducted fan during hovering.

Thanks for the help.
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
