Research areas description

Over the past ten years Computational Fluid Dynamics (CFD) has progressed to the point where its predictive capability is limited by the fundamental fluid mechanics knowledge (“turbulence”) imbedded in it. A consequence is that we are fast approaching the point where this will set limits on the efficiency of devices that engineers can design with the current CFD tools.The Laboratory for the Study of Fundamental Fluid Mechanics (FFM) issues to understand the limitations of current models imbedded in CFD tools and to unleash them using ‘a priori model testing' to improve and extend the reach of the imbedded knowledge for this class of problems to meet anticipated needs of industry for the economic and social benefit of the country.

The Laboratory for the Study of Fundamental Fluid Mechanics (FFM) issues to understand the limitations of current models imbedded in CFD tools and to unleash them using 'a priori model testing' to improve and extend the reach of the imbedded knowledge for this class of problems to meet anticipated needs of industry for the economic and social benefit of the country. The laboratory will be use to analyse complex physics in simple geometries in laminar, transitional and turbulent flow regimes to challenge the prediction capability of commercial CFD code and to foster modeling activities in this field. There is four classes of flows important to the engineering applications:

1) Stability of swirling flows

2) Rotating flow turbulence

3) Transitional wall flows

4) Elastic turbulence.

Press review about Fluid Dynamics Laboratory (LADYF)

February 7, 2022, CScience IA, Une dentition parfaite grâce à l’IA ? François Guibault, professeur titulaire au Département de génie informatique et génie logiciel à Polytechnique Montréal, revient sur le prototype de génération de surfaces en 3D, actuellement développé par son équipe, et qui s'appuie sur un outil informatique basé sur l’intelligence artificielle pour concevoir des couronnes dentaires.
