Curriculum Vitae

2002 MSc. Grade in Chemical Engineering (Faculty of Chemical and Food Technology, Slovak Technical University)
2006 PhD. in Chemical Engineering (Faculty of Chemical and Food Technology, Slovak Technical University)

Tasks

  • Modeling of 3D immiscible flows in the field of droplet generation from laminar jets. The basis of the deliverable simulation tool is defined by the following methods: Level Set approach, PDE-based reinitialization, Discontinuous Galerkin FEM.
  • Modeling of 3D non-Newtonian flows in twinscrew extruders. In the framework of the related project special Fictitious Boundary and Grid Deformation methods are to be implemented.

Research Interests

  • multiphase flow (l--l,l--g,s--l)
  • dispersed flow simulation based on population balance models
  • turbulent flow (k-epsilon)
  • Chemically reacting flow modelling
  • MPI-based parallelization (domain decomposition)
