Non‐classical large eddy simulation (LES) approaches based on using the unfiltered flow equations instead of the filtered ones have been the subject of considerable interest during the last decade. In the monotonically integrated LES (MILES) approach, flux‐limiting schemes are used to emulate the characteristic turbulent flow features in the high‐wave number end of the inertial subrange region. Mathematical and physical aspects of implicit sub grid scale modelling using nonlinear flux‐limiters are conveniently addressed using the modified LES‐equation formalism. In this study, the performance of MILES is demonstrated as a function of the flux‐limiting scheme in selected representative case studies. Published in 2005 by John Wiley & Sons, Ltd.
