Low Reynolds 2D Airfoil simulation
 

Hello Everyone,

Please pardon me. I just recently started using the student version of ANSYS for my class project. I would like to do a 2D flow simulation around the NACA 4412 airfoil with a Reynolds of 50,000. Before I do this, I decided to do the exact simulation i found on a website (link to the website is at the end of the page) using the NACA 4412 and matching their Reynolds of 30,000. A YouTube video was able to help me set up my simulation but after simulation, my CL and CD does not match what the website got.

1. What am I doing wrong? Here is my mesh Attachment 52816

Attachment 52817

2. Is it possible to change the chord length from 1 meter? I would like to make it .175 meters

3. Should I use Inviscid flow or Laminar flow considering the fact that I am in the low Reynolds region
