Position: Postdoctoral Fellow
Institution: Paul Scherrer Institut
Location: Villigen, Aargau, Switzerland
Duties: Conduct research in the area of cross-scale modelling of multiphase flow (boiling) in complex heterogeneous materials, including conjugate heat transfer and surface reactivity with application to nuclear reactor flows; Coupling and upscaling of molecular dynamics simulation results (contact angles) to the in-house Lattice Boltzmann numerical solvers and subsequent upscaling of results to macroscopic multiphase solvers for pool boiling simulations. The framework of the in-house scientific multiscale codes will be the basis for further developments; 2D/3D numerical simulations of bubble interaction with realistic surface roughness using the CPU and GPU capabilities of the in-house codes; Co-development of codes, including benchmarking and validation; Publication of results in journals and conferences
Requirements: PhD degree in Mechanical or Nuclear Engineering/Natural Sciences/Environmental Sciences; Experience in numerical simulations, fluid dynamics and multiphase flows (ideally with lattice Boltzmann method); Strong experience in numerical modelling and fluid dynamics, as well as programming experience (C/Cuda/Python); Very good command of English is required (spoken and written); Team player able to work independently
