The Laboratory of Combustion and Acoustics for Power & Propulsion Systems (CAPS) in the Department of Mechanical and Process Engineering invites applications for a PhD position on the direct numerical simulation of hydrogen and hydrogen-enriched combustion. The PhD work is part of the European H2020 project Center of Excellence in Combustion (CoEC).
The Center of Excellence in Combustion is a collective research and innovation effort of combustion research laboratories across Europe to exploit Exascale computing in order to address fundamental challenges related to the simulation of combustion systems. In line with the decarbonization goals of the European power and transport sectors and the European roadmap to achieve net-zero greenhouse gas emissions by 2050, the center will promote a core of scientific and technological activities aiming at extending the state-of-the-art in combustion simulation capabilities through advanced methodologies enabled by Exascale computing.
Simulations of pure hydrogen and hydrogen-hydrocarbon blends will be performed to assess the effects of hydrogen chemistry and thermodiffusive instability in turbulent hydrogen and hydrogen-enriched flames. Development of the GPU version of our spectral element low Mach number reactive flow solver will be needed to implement a high-order operator splitting scheme and on the fly adaptive chemistry to speed up the integration of the chemical source term. Subsequently, the effects of composition and turbulence characteristics on the structure and dynamics determining the fuel consumption rate at high temperatures and computationally-affordable high pressures will be investigated using large-scale direct numerical simulations (DNS) in open and closed constant volume domains. The closed-domain simulations will enable the investigation of the effect of confinement on the flame structure and propagation with particular focus on the processes related to the interaction of the flames with the walls.
Applicants for this position are expected to have an excellent MSc degree or equivalent in mechanical engineering or physics. Ideally, you have experience and a proven record in one or more of the following: high-order numerical methods and programming, combustion simulation, and fluid dynamics. A solid background in math, physics and programming is required. We are looking for highly motivated, committed, and creative individuals with excellent communication skills able to work in a team. The position is available from October 1st 2020.
We look forward to receiving your online application with the following documents:
