International audience; Delaying laminar-turbulent transition is considered a crucial issue with respect to the reduction of airplanes environmental impact, allowing to reduce skin friction drag and thus, fuel consumption. As part of this thematic, b

This paper presents an extension of the γ-Rθt~ transition model of Menter et al. (2006) that aims to take into account the effect of a specific type of surface roughness on the transition location. This was done by implementing the roughness transi

International audience; With the objective of inserting laminar–turbulent transition prediction inside computational fluid dynamics codes (Navier–Stokes solvers and boundary-layer codes), a physically based transition criterion for laminar–turb

Laminar-turbulent transition remains a critical issue in a number of cases, including drag reduction, performance prediction of high-lift systems, improved accuracy in general computational fluid dynamics, and reduction of computation cycles for deve

Laminar-turbulent transition appears in high-lift configurations through instabilities, attachment-line contamination, or separation. Its prediction may improve the estimation of maximum lift and allows the extrapolation from wind-tunnel measurements

This paper presents RANS computation results on the highly-loaded low-pressure turbine blade T106C using the Display Formulaγ-Rθt~ transition model. First, a setup methodology is described, addressing key points such as inlet values for the turbule

The experimental and numerical transitional interactions in hypersonic flow are studied. The experiments were performed on a hollow cylinder-flare model in the ONERA R2Ch wind tunnel at a Mach number of 5 and for varying stagnation pressure. Wall pre

Performance of transport aircraft in high-lift conditions is directly related to the maximum lift. However, most of the high-lift tests are carried out at subscale conditions, and performance is then derived by extrapolation to flight Reynolds number
