The prediction and investigation of very high Reynolds number turbulent wall flows pose a
significant challenge: experimental studies and large eddy simulation (LES) are often …

Purpose Fluid flows in pipes whose cross-sectional area are increasing in the stream-wise
direction are prone to separation of the recirculation region. This paper aims to investigate …

This work studies the effects of skin-friction drag reduction in a turbulent flow over a curved
wall, with a view to understanding the relationship between the reduction of friction and …

Turbulent flow over a series of increasingly high, two-dimensional bumps is studied by well-
resolved large-eddy simulation. The mean flow and Reynolds stresses for the lowest bump …

The separating and reattaching flows and the wake of a finite rectangular plate are studied
by means of direct numerical simulation data. The large amount of information provided by …

Abstract The analysis of Direct Numerical Simulation data of the separating and reattaching
flow over a blunt bluff body with sharp edges, reveals the presence of negative turbulence …

Exact budget equations for the second-order structure function tensor. In a third example, the
AGKE are computed for a separating and reattaching flow. The process of spanwise-vortex …

Large-eddy simulations were used to investigate unsteady flows around a wall-mounted
hemisphere as the Reynolds number (Re, based on the diameter of the hemisphere D) …
