The experiments carried out within the AFRODITE[2] project are aimed at exploring the effectiveness of properly shaped velocity miniature vortex generators in delaying transition to turbulence in a boundary layer. The present work details the direct numerical simulation setup designed to support and reproduce the AFRODITE experiments and provide results showing that the proposed DNS is in good agreement with the experiments. The results of the DNS also show that even a minimal delay of the transition point results in an overall gain in terms of drag when MVGs are installed on the plate.

Abstract
The experiments carried out within the AFRODITE[2] project are aimed at exploring the effectiveness of properly shaped velocity miniature vortex generators in delaying transition to turbulence in a boundary layer. The present work details the direct numerical simulation setup designed to support and reproduce the AFRODITE experiments and provide results showing that the proposed DNS is in good agreement with the experiments. The results of the DNS also show that even a minimal delay of the transition point results in an overall gain in terms of drag when MVGs are installed on the plate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
