Hello everyone.

I am currently working on my university dissertation, and I've decided to do it on component cooling through NACA Ducts (submerged inlets). I design my models on Solidworks and import them to Ansys, however I have absolutely no idea what i'm doing!
Would anyone be able to help me out? I have tried finding youtube videos and websites or images, but I can't find anything that seemingly relates very well!

Any information would be incredibly useful!

Thank you to anyone in advance ,
Andy

Well this is an extremely vague request.

Do you have a background using and/or studying computational fluid dynamics? You need to understand what a CFD code does and hence the capabilities and limitations of the tool. Then, identify what you are actually trying to achieve with your research. Is this possible with a CFD code? Or even necessary?

You say "component cooling through NACA ducts." What is the exact research problem/question? You need to significantly sharpen your focus before you start throwing models into a CFD solver. Garbage in = garbage out.

Thanks for the feedback — that’s fair.

The aim of my dissertation is to analyse the drag performance and pressure distribution in and around a NACA duct under flow conditions representative of a small UAV or drone. The goal is to evaluate whether NACA ducts are an effective cooling solution for internal components without causing excessive aerodynamic drag.

I’ll be using ANSYS Fluent for the simulations, focusing on modeling airflow over and through the duct integrated into a surface, not just through an isolated negative mold. I want to capture how the external boundary layer interacts with the inlet and how that affects both the pressure recovery and the cooling efficiency.

If you have any suggestions on how to best set up the model or boundary conditions to accurately represent this kind of coupled internal–external flow, I’d really appreciate the guidance!
