Default Temporal differencing for LES

Posts: n/a
Hi everyone, I would like know which temporal differencing scheme is better for Large Eddy Simulations?

For coupled density-based solvers, please compare CGS-like matrix solver with dual-time integration(or Newton method) amd explicit time methods such as Runge-Kutta.

For incompressible pressure-based solvers, which is better between SIMPLE-family and Fractional step or MAC methods?

Waiting for your kind answers..
