I'm solving the stationary non-compressible task so I use simpleFoam and compare the results with the experiment data. The number of Reynolds in my problem shows that a flow is a laminar. But, my pressure values are on average 65% of what they should be. So, I want to try the turbulence model. I have a question: is it correct to use the turbulence model, if the viscosity shows that flow is a laminar?

And can you please advise where I can find simple/simplified explanations/discussions of RAS and LES models?

Run with turbulence model and verify that turbulent viscosity (mut) is small?

Check out Aiden Wimshurst's Channel on youtube. It is an excelent resource for all sorts of cfd topics
