The Faculty of Science, Technology and Medicine (FSTM) contributes multidisciplinary expertise in the fields of MathematicsPhysicsEngineeringComputer ScienceLife Sciences and Medicine. Through its dual mission of teaching and research, the FSTM seeks to generate and disseminate knowledge and train new generations of responsible citizens, in order to better understand, explain and advance society and environment we live in.

Your Role…

In cooperation with international partner organizations the research team Applied Thermodynamics of the University of Luxembourg is developing Multiphase Fluid Dynamic Tools and Methods. Lattice Boltzmann is a method for numerical simulation of flows based on a discrete grid describing the flow properties by probability distributions. Multiphase Lattice Boltzmann allows modeling of flows where multiple fluids or phases are present simultaneously, such as gas-liquid mixtures or multicomponent flows. It is a powerful method to study complex flow phenomena.

The successful candidate is expected to perform the following tasks:

  • Development of Python based Lattice Boltzmann Multiphase Code to simulate Multiphase Fluid Dynamic Problems
  • Run calculations and validate the results
  • Disseminate results through scientific publications and talks at conferences
  • Support for teaching programs
What we expect from you…
  • Master degree in mechanical-, process engineering, physics or informatics.
  • Experience in Fluid Dynamics
  • Experience in programming (Python, Matlab, C/C++)
  • Fluent in speaking and writing English
In Short…
  • Contract Type: Fixed Term Contract 36 Month (extendable up to 48 months if required)
  • Work Hours: Full Time 40.0 Hours per Week
  • Location: Kirchberg
  • Internal Title: Doctoral Researcher
  • Job Reference: UOL05911
  • Employee and student status

The yearly gross salary for every PhD at the UL is EUR 39953 (full time)

How to apply…
