CFD expert: aerodynamics, heat transfer, etc.

I am an American expat, expert in computational fluid dynamics (CFD) and programming, especially in physics, engineering, and related fields. I have worked with various programs since beginning my CFD career in 2006: OpenFOAM, Fluent, and various homemade solvers. I have worked in various sectors: aerospace, energy, materials engineering; and I have worked with various physics from micro- to macro-scale: laminar/turbulent, solidification, heat transfer, multiphase, etc.

Publications

Model reduction for a variable geometry

Proceedings of the World Congress on Engineering 2011
A methodology is presented to create reduced models of fluid thermal problems with varying geometry. The methodology is applied to the nonisothermal backward-facing step problem, depending on three parameters: the Reynolds number, the wall temperature, and the step height. Various snapshots are calculated using a computational fluid dynamics (CFD) solver. The resulting reduced order model provides solutions that compare well with their CFD counterparts, in a much smaller CPU time.

A computationally efficient reduced order model to generate multi-parameter fluid-thermal databases

International Journal of Thermal Sciences
A reduced order model (ROM) is proposed to generate multi-parameter databases of some fluid-thermal problems, using a combination of proper orthogonal decomposition, a gradient-like method, and a continuation method. The methodology is illustrated with the non-isothermal flow past a backward-facing step in the laminar regime, which is a representative problem, related to the engineering design of micro-heat sinks.

Model reduction in the back step fluid-thermal problem with variable geometry

International Journal of Thermal Sciences
A reduced-order model (ROM) is created for variable geometry fluid–thermal problems using the method of snapshots. Proper orthogonal decomposition (POD) modes are obtained from the snapshots and are used to define expansions of the flow variables. The associated POD mode amplitudes are obtained minimizing a residual. This methodology is illustrated addressing the problem of heat transfer downstream of a backward facing step in the 2-D steady, laminar regime.

Off-eutectic binary salt finite volume method

Energy Procedia
Non-linear phase diagrams for binary compositions are coupled with Thétis, a finite-volume solver, to calculate charge/discharge solutions for an off-eutectic salt thermal energy storage candidate. A methodology is presented to include non-linear phase diagrams and locally calculated thermal properties in Thétis.

Thermal storage tank at high temperature

Spanish patent ES2567002B1
High temperature thermal storage tank, comprised of stacked monoliths with channels that allow the heat transfer fluid to pass through the monoliths while exchanging heat with the monoliths. Various levels of monoliths are created so as to limit heat transfer between monoliths by radiation and conduction. Intermediate layers of low emissivity material may be added to further reduce radiation heat transfer.

Impregnation of composite materials: a numerical study

Applied Composite Materials
In order to design an efficient manufacturing process able to impregnate ceramic matrix composite material fabrics well, numerical simulations are used to design the process as well as the slurry. Thetis, a finite volume solver, is expanded to take into account capillary pressures on the mesoscale. The resulting tool is used to investigate the effect of varying the slurry parameters as well as process input parameters for two different processes: open bath impregnation and wet lay-up.
