Capgemini and CSTB will present a total of 3 papers at 3AF conference in Toulouse, France at the end of March 2022. They focus on Experimental data acquisition during InVIGO (Stereo-PIV) Wind Tunnel vs CFD comparison for vortex properties Wind angle and scale effect on vortex characteristics The program is available below: https://www.3af-aerodynamics.com/

InVIGO has presented results during 3AF 2020+1 congress on April 12, 2021, entitled “Unsteady simulation of intake ground vortex ingestion in real wind tunnel condition”. The full article and presentation slides are available here: Article Presentation

InVIGO will present results during 3AF 2020+1 congress in April 2021. Results regarding ground vortex on both isolated nacelle and wind tunnel configuration will be compared. The paper is a common Altran/CSTB article and will describe the experimental set-up in addition with numerical results. Similar ground vortex results are obtained for the chosen operating point. […]

First InVIGO test campaign was successfully carried out in CSTB facilities in December 2020. More than 10 days of wind tunnel tests allowed acquiring a lot of vortex data on around 50 wind/ground clearance configurations. The 250 kW fan permitted to reproduce required engine flows for all expected combinations of engine intake and crosswind velocities. […]

First methodology activities related to Wind Tunnel testing and CFD have been carried out by CSTB and ALTRAN. Corresponding reports will be delivered soon. Many interesting conclusions were drawn : Unsteady simulations have to be considered for some operating points Complementary ground vortex capture methods have been set up Cutting-edge visualization means will be effectively […]

Abstract accepted for NAFEMS France 2020 congress “Benefit of mesh adaption vs. conventional CFD approach for nacelle aerodynamics with ground effect”.

First technical work package concerning state-of-art regarding ground vortex is almost finished.

InVIGO Kick-Off meeting took place at Safran Aircraft Engine facility on October, 11 2019
