RUM2021 ​​​​​​​RUM2021-Spain ​​​​​​​XFlow 

During the 2021 EuroWest (Spain) RUM we welcomed Jorge from INTA. Jorge presented "Lattice-Boltzmann simulation of a deflecting Krueger device" - the abstract is below. 

Jorge has a PhD in Aerospace Engineering from the Politechnical University of Madrid. He is currently a senior research engineer at the computational aerodynamic branch of INTA (National Institute of Aerospace Technology) in Spain. His work is related with CFD development and application to external aerodynamics. He has participated in several European research projects related with high lift aerodynamics.

"We present results obtained with XFlow software to predict the unsteady aerodynamics of a moving Krueger device. 

Laminar flow wing technology requires specific high-lift concepts in order to keep the flow on the upper surface unperturbed in cruise conditions. One possible solution is to replace the classical slat element by a folded Krueger device. In this talk, we show preliminary results of the application of the Lattice-Boltzmann software XFlow to the prediction of the unsteady aerodynamic flow present during deployment/retraction of a Krueger device. The results presented in this talk have been obtained within the EU-project UHURA, which is dedicated to the validation of flow simulation methodologies for the prediction of moving high-lift devices."
