There is some mention of a ducted fan example in the instructions, but I couldn't see the code for it anywhere or how it was generated. |

Hi Anant! I did a proof of concept simulating a shrouded rotor with the wing actuator surface model (ASM) in this simulation: LINK. However, I didn't feel like this was the appropriate model to capture the effects of a surface in very close proximity to the blade tips, so I moved forward doing validation (perhaps the wing ASM could still be used to roughly capture some effects). Instead, we developed a new ASM using a panel method which we showed in the AVIATION 2023 paper: [Video] [Paper]. This model works well for ducted fans, but more development and validation is still underway. That work is currently in the flowpanel_prototype branch. If you are interested in helping the development and validation process, we could send you the scripts that run the simulations shown in the paper for you to start running your own simulations. |

Hi Ed,
My colleague Tenon Charly Kone and I would like to help with the development and validation of a ducted rotor model. You had mentioned that would be willing to share the scripts used to run the ducted rotor sims in your 2023 AIAA Aviation paper “Vortex Particle Method for Electric Ducted Fan in Non-Axisymmetric Flow.” That would be a great place to start. We will familiarize ourselves with the script ad we can follow up with a virtual meeting.
Regards
Anant

Hi Anant!
I did a proof of concept simulating a shrouded rotor with the actuator surface model (ASM) in this simulation: LINK<https://www.youtube.com/watch?v=Bf4pIt7oi5k> . However, I didn't feel like this was the appropriate model to capture the effects of a surface in very close proximity to the blade tips, so I didn't even bothered in doing validation (perhaps ASM could still be used to roughly capture some effects).
Instead, we developed a new ASM using a panel method which we show in the AVIATION 2023 paper: Video<https://www.youtube.com/watch?v=ebOW4aLGlMA>Paper<https://scholarsarchive.byu.edu/cgi/viewcontent.cgi?article=7676&context=facpub>. This model works well for ducted fans, but more development and validation is still underway. That developments is in the flowpanel_prototype branch<https://github.com/byuflowlab/FLOWUnsteady/tree/flowpanel-prototype>. If you are interested in helping the development and validation process, we could send you the scripts that run the simulations shown in the paper for you to start running your own simulations.

@kont1901 @agrewalks, it would be great if you guys could help validating the ducted fan model. I believe there's great potential using panels for the duct and actuator line for the rotor as shown in the paper (unfortunately, I have been busy with other things at work after the AVIATION 2023 paper). @cibinjoseph recently picked up the ducted fan model to continue working towards a journal paper. Perhaps we can do a collaboration jumping together in the same paper. I'll send you my email over LinkedIn to continue the conversation through email. |

Congratulations on this very versatile and powerful framework! Can the Actuator Surface Model be used to define a duct around a fan?
Thanks
