Default Estimation of numerical diffusion

Hallo! CFD friends,

I have a very general question about the estimation of the numerical diffusion. Is it possible to some way to filter numerical diffusion from the physical diffusion? Or does there exist a method to fix the extend or range of numerical diffusion?

Any idea in this direction will be highly appreciated.

Greetings Varghese
