For turbulent flows in porous media, it is often assumed that the irregularity of the matrix would not affect the macroscopic, double-averaged (in time and space), parameters of turbulence. Hence, to improve currently used modelling techniques, the …

As most papers in the community of double averaging neglect the effects of commutation errors, we demonstrate in this featured article that the effects are significant enough to affect the solution.
