What is mathematical modelling?

Mathematical modeling is a technique used by engineers and scientists since the early ages of science. Today, with the advent of extremely powerful computers, the tools available to solve these models have taken a new direction. Mathematical modeling and numerical simulation have become two very active fields, complimentary to each other and often confused by many. Our group develops mathematical models of complex fluid flow involving chemical reactions, porous media, electromagnetic fields, radiative heat transfer, multiphase flow, to name a few. All these phenomena can be represented using physical and chemical laws through sets of strongly coupled sets of equations. These may be non-linear partial differential equations, integro-differential equations, difference equations, etc... that must be transformed and combined. Some of the tools that are used to solve these complex coupled systems of equations come from the rich field of the Computational Fluid Dynamics (CFD), and the solution using these tools is often named numerical simulation. For many of the phenomena involved in the modeling of the complex flows we have to develop our own methods that are not included in traditional CFD methods, for example to include the behavior of nanoparticles, to calculate transport and thermodynamica properties of plasmas, heterogeneous catalysis, etc...

Pr. Proulx has been active in the mathematical modelling of complex flow phenomena for more than 20 years, he published the first paper addressing the problem of two-phase inductively coupled plasma-particle interaction effects back in 1983. He has been involved in the development of mathematical models since, has published  over 60 journal papers and a hundred invited and contributed conferences on the subject of complex flow phenomena modelling. He has applied the models he developped to many different fields ranging from biological flows, to electrochemical reactors, and supersonic plasma jet. He is also recognized as an expert on the production of nanomaterials in thermal plasma reactors and thermal plasma process modelling.
