I am currently modelling a concept aircraft and a major part of my project is to analyse the behaviour of its engines. From my research, I found that previous studies model them using an actuator disk and use it to apply a pressure drop where the fans of the engines are.
I am having troubles in trying to figure out if this sort of an actuator disk model is even possible in SimScale. I found a way to model an actuator disk but I’m unsure if this is what I need since it’s only letting me control the velocities. There is also an option to model a rotating volume here but I don’t quite understand if I’ll be able to replicate their simulations using this approach.
A more recent study also used a source distribution model and inlet-outlet boundaries for modelling the engines but I have never came across these approaches during my studies.
These are the papers I’m looking at:
Hall, DK, Greitzer, EM, Uranga, A, Drela, M, & Pandya, SA. “Inlet Flow Distortion in an Advanced Civil Transport Boundary Layer Ingesting Engine Installation.” Proceedings of the ASME Turbo Expo 2021: Turbomachinery Technical Conference and Exposition . Volume 1: Aircraft Engine; Fans and Blowers; Marine; Wind Energy; Scholar Lecture . Virtual, Online. June 7–11, 2021. V001T01A010.
In case the papers are still unavailable to the public here’s their explanation of the actuator disk used in the comparison study:
If you have any ideas please let me know. I’ve been using SimScale since I started my Master’s project and I wouldn’t want to switch at this stage.
