Transitional–turbulent spots bridge the deterministic laminar state with the stochastic
turbulent state and affect the transition zone length in engineering flows. Turbulent spot …

The paper addresses modelling concepts based on the RANS equations for laminar-
turbulent transition prediction in general-purpose CFD codes. Available models are …

A nominally-zero-pressure-gradient incompressible boundary layer over a smooth flat plate
was simulated for a continuous momentum thickness Reynolds number range of 80≤ …

Bypass transition in an initially laminar boundary layer beneath free-stream turbulence is
simulated numerically. New perspectives on this phenomenon are obtained from the …

The effect of high levels of free-stream turbulence on the transition in a Blasius boundary
layer is studied by means of direct numerical simulations, where a synthetic turbulent inflow …

LARGE eddy simulations (LES) and direct simulations have been successfully used over the
last decade to study turbulent academic ows, leading to signifi cant improvements of both …

In the present paper, direct numerical simulation (DNS) studies of the compressible flow in
the T106 linear cascade have been carried out. Various environmental variables, ie …

A new high-resolution code for the direct simulation of incompressible boundary layers over
a flat plate is described. It can accommodate a wide range of pressure gradients, and …
