Abstract: In this talk, we will provide an overview of our research activities in the area of modelling and optimization of energy systems.

The first part of the presentation briefly introduces two main aspects of our research work in this area, namely: (i) Modelling transport phenomena in the gas diffusion layer (GDL) of proton exchange membrane (PEM) fuel cells, and (ii) Multi-objective optimization of wind farm layouts.

In the second part of the presentation, we discuss in more details our work in modelling transport phenomena in porous materials. First, we will introduce briefly the Pore-level modelling approach for heat and fluid flow in porous materials using the lattice Boltzmann method. Results of our pore-level simulations on the effects of pore structure, porosity, and porosity distribution on macroscopic hydrodynamic and thermal properties of GDL samples will be presented. Theoretical aspects of flow in porous materials, including the open-porous interface boundary condition and effect of inertia in porous materials will also be addressed.

The outcomes of these simulations are used to characterize the different types of GDLs that are currently used in the manufacturing of fuel cell stacks.
