[Osama Maddani]

Hello
I am Osama Maddani, a BSc Mechanical Engineering graduate and an MSc student in the University of Benghazi.

I have read published work affiliated to Ansys on SAE on the Ford Ka titled "Aerodynamic Performance Prediction of a Car using GEKO Turbulence Model and Application of Gradient Based Optimisation for Improving Aerodynamic Drag", doi:10.4271/2021-26-0353.
I am actually working on the GEKO model too for a few reasons, 1. for my Master's degree thesis, 2. for publishing research papers, I have done the validation and mesh testing using the DrivAer car model and geometry made by TUM https://doi.org/10.1115/FEDSM2012-72272 .

Actually changed the CSEP value to 1 which is what the following Ansys tutorial recommends Aerodynamic Analysis of an FSAE Car using Ansys Fluent - YouTube  for a formula SAE car,  it has given good agreement with the experimental values for the Notchback configuration.

I have a few questions to help me hopefully publish in SAE, if you have the time to please help me out:

1.Is it ok to mention specific car brands ? the paper mentioned the Ford Ka, but I see some other studies that avoid that and mention names like a "sports car" for an obvious Honda CRX DelSol model in this study https://doi.org/10.3390/en12244697, I have access to 3D scanning and make CAD models of actual cars based on those scans, so I might make something.

2.Is it considered too simple of an idea or not worth of testing to test generic aerodynamic accessories effectiveness that are for sale but have no proof of their function, I will give you two examples:

1. I have a 3D scan of a wing element made by NRG which I tested on the DrivAer car and developed an upgraded endplate for over the one that came with the wing, which actually has more lift to drag than the original endplate, is it considered a worthy study of publication? And is it ok to mention the NRG brand or shall I just say a "readily available commercial aftermarket wing"?
   
   
2.  I have a 3D scan of a Chevrolet Cruze and a 3D scan of a Generic 56" wing made by different several manufacturers in China but has the same shape, informally known as an "eBay wing" , it does have a 3D twisted profile. 
   I tested that and also with Vortex generator fins on the roof like Mitsubishi did .

   I am asking if this study is worth publishing in SAE ?
   
   Should it be "testing the viability and function of a generic commercial wing and optimum angle of attack on a Chevrolet Cruze/ Commuter Sedan car body " ?
   
   Or shall it be "Improving the aerodynamic performance of a Chevrolet Cruze/Generic Sedan " ?
   
   Or another suggestion is " testing the viability of aftermarket commercial aerodynamic accessories (wing and fin vortex generators) on a Chevrolet Cruze/Commuter Sedan car " ?
   
   The second question is two fold as I am asking about mentioning the commercial brands and the viability of the topics.
   
   

I would really appreciate if you help me out, as I have never published before in a very good journal, I believe the work quality is eligible, but I just need some guidance.

Best Regards,

Osama
