Bruno Blais
Associate Professor @ Polytechnique Montréal
About
I am a professor in the Department of Chemical Engineering at Polytechnique Montréal, where I lead the CHAOS (Chemical engineering High-performance Analysis, Optimization and Simulation) Lab. My research sits at the intersection of computational fluid dynamics (CFD), numerical methods, and high-performance computing, with a particular focus on particulate and multiphase flow systems. I am one of the principal developers of deal.II, a widely used open-source finite element library that powers research and engineering simulations across academia and industry worldwide. I am also the lead developer of Lethe, an open-source CFD software built on top of deal.II, designed for high-fidelity simulation of fluid dynamics and particle-laden flows using modern numerical approaches. At the CHAOS Lab, I mentor a team of graduate students and postdoctoral researchers working on cutting-edge problems in simulation science — from granular flows and mixing to free-surface dynamics and beyond. Our work combines rigorous mathematical modeling with scalable software development, bridging the gap between fundamental research and real-world engineering applications. I am passionate about open-source scientific software and the role it plays in making high-quality simulation tools accessible to the broader research community. If your work touches on CFD, multiphase flows, numerical methods, or scientific computing, I'd be glad to connect.

Experience

Assistant Professor
Assistant Professor in the Departement of Chemical Engineering. My research activities center on the simulation of complex multiphase flows (solid-liquid, solid-gas) in chemical processess using novel methods based on computational fluid dynamics and the discrete element method.

Research Officer
Boucherville
Research officer in computational fluid mechanics and numerical modeling. Development, verification, validation and application of finite element and finite volume methods to the study of a variety of flow (incompressible, subsonic, supersonic, free surface, multiphase) and heat transfer problems.

Ph.D Candidate - Vanier Graduate Scholar
Thesis title : Euler-Lagrange Modeling of Solid-Liquid Flows in Stirred Tanks and Transport Processes The aim of this project is to develop a modelling scheme to allow for a fine study of solid-liquid flows in critical unit operations such as pipeline transport and stirred-tanks mixing. It is proposed to combine the Finite Volume Method (FVM) with the Discrete Element Method (DEM) in a CFD-DEM formulation in order to gain insight into the physics of solid-liquid mixing. This is achieved via the extension of the CFDEM framework that combines LIGGGHTS and OpenFOAM. The final aim is to accurately predict critical macroscopic quantities such as power consumption, just-suspended speed, torque and the distribution of particles.
