Overview

Christopher Leonardi, Ph.D., is a Lecturer within the School of Mechanical and Mining Engineering.

His research effort in this post, in collaboration with some of the world's largest oil production and services companies, is currently targeted at the development of large-scale numerical models which can be used to provide insight into the complex characteristics of multiphase fluid flows in oil and gas reservoirs. This has included the creation of a computational framework which uses micro-CT images of core samples and a range of numerical methods to determine the permeability of reservoir rocks, and the combination of non-Newtonian fluids and suspended particles to simulate the behavior of proppants in hydraulic fractures. Projects in the immediate future will include capturing the behavior of thin films in simulations of multiphase flows in porous media as well as the transport of methane in low porosity shale.

Research Interests

  • Research Interests
    Dr. Leonardi's general research interests include, in addition to multiphase flows, computational modelling of fluid-structure interaction (i.e. particle suspensions) with non-Newtonian fluids, and high performance parallel computing using shared memory multicore architectures. Particular fields of expertise include the lattice Boltzmann method (LBM) for fluid flows, the discrete element method (DEM) for discontinuous systems, and the finite element method (FEM) for solid mechanics problems.
