Master Thesis - Nozzle Design for Spray Shape Optimization

Job description Focus will be on running simulations on a given geometry and the postprocessing of model results. However, if interesting new design ideas evolve, other geometries could be included if time allows. The simulations are done in two steps. Firstly, a 3-fluid (liquid, fuel vapor and air) nozzle flow simulation is conducted and time resolved flow results from the nozzle orifice are extracted. Secondly, these results are transferred to a Lagrangian spray model for high pressure liquid injection, from which the combustion performance is assessed. The simulations are done using the AVL Fire 3D CFD software package. We work in a Linux environment with very powerful hardware and a simulation is usually completed in 10 hours. Postprocessing is usually done with scripts (e.g. bash, awk, Perl, Python and Matlab) and a plotting program (e.g. XMGRace or GnuPlot). Education/program/focus Master of Science in Mechanical Engineering, Engineering Physics or similar, with specialisation in modelling and simulation.
