I’m trying to match drag and lift coefficient vs. alpha using a NACA0010 with the results online on airfoiltools.com. My trend looks like it is matching very well, but the values are somewhat off. What values/factors in the simulation designer should I change in order to get the values to be somewhat closer?
Here’s a link to my simulation on simscale: [Deleted by author]
Actual coefficient is the data from airfoiltools.com
Experimental coefficient is the data I got using simscale
I have had a look at all your models and what I would definitely do is to increase the size of your bounding box as your domain is way too small! Also add layers to your NACA profiles.
Also have a look at some NACA simulations in the Public Projects section that can help you to set up your project. I am sure you will get pretty good results if you increase the size of the domain as well as adding layers.
@ejohnathon could you try re-running your simulation now? There was a fix in the latest release that is related to modeling of no-slip walls when using turbulence models. Looking at your simulation setup, it might affect your results as well.
The suggestion from @jousefm to increase the domain size still holds though.
