I need to develop a model in CFD that accurately represent the fluid flow in a huge pipe. Standard Eulerian techniques cannot solve the problem accurately because the range of time-scales and length-scales in the problem is so broad. Moreover, Lagrangian methods are difficult to resolve the molecular scale.

So I think that the better approach to the problem it will be the Euler/Lagrange approach.

What is your opinion?

Why you wrote that??
