Abstract: Abstract Direct numerical simulations of cube-roughened rough-to-smooth channel flows are performed with the objective of studying the response of turbulence statistics in the developing flow over smooth walls. Non-equilibrium effects persist and the global recovery… read more here.

Abstract: The turbulent flow over an array of cubes mounted on one of the walls of a channel has been investigated using direct numerical simulation for cube spacing that ranges between 2.0 and 4.0. The Reynolds… read more here.
