Research Activities

The research activities of our group lie primarily on the fields of Theoretical and Computational Fluid Dynamics with particular emphasis on the fundamentals of multi-phase flows, complex fluids, and reacting flows. Our activities cover: i) development of models for the flows of interest, ii) algorithm development and implementation for these models, iii) software verification and validation, and iv) detailed numerical studies and simulations via high performance computing.

As regards multi-phase flows, our current research activities focus on fluid-saturated granular materials with application to sediment transport in coastal and fluvial environments, flows of heterogeneous mixtures and powders with application to the transport and storage of bulk agricultural products and pharmaceuticals,  flows through porous media with application to fuel cells and industrial filters,  turbulent liquid-vapor pipe flows with application to the Pressurized Thermal Shock Problem of nuclear power plants, etc.

As regards reacting flows, we are currently pursuing research on both subsonic and supersonic combustion. Examples include the study of turbulent premixed flames, porous-media combustion with application to forest fires and fluidized beds,  thermal explosions, ignition and propagation of gaseous detonations with application to Pulse Detonation Engines, modelling and simulation of two-phase detonations with application to granular explosives, and others.

Funding of these ongoing projects is provided by the European Union, the National Fund of Scientific Research of Belgium (FNRS), BelV: a subsidiary of the Federal Agency of Nuclear Control of Belgium, and by private companies.
