Dear friends, I am a postgraduate student,

several days ago, l found a paper on google scholar, which is about combustion noise simulation using the hybrid(CFD/CAA) method.

In the paper, the author claims that he uses the LES(Large-eddy simulation) model to calculate the combustion flow field without any special wall treatment, even no mesh refinement is employed near the walls.

I am quite confused about it, How can he ignore the boundary layer effect to the accuracy of the LES simulation.

The paper's name is "Combustion Noise Prediction Using Linearized Navier–Stokes Equations and Large-Eddy Simulation Sources".
