I started my career as PhD student at Vienna University of Technology, Chemical engineering department at 2014. I started using CFD (Ansys Fluent) during my bachelor and continueid with programming CFD (A CFDEM code in fortran for modelling fluidized beds) for my master thesis. My first experience with OpenFOAM backs to 2012 at TU Wien with prof Harasek Team (www.cfd.at). As I started to learn OpenFOAM I also documented my findings as a series of step by step tutorials. At the moment I'm using OpenFOAM for dealing with chemical engineering problems in both aspects as a user and also developer. I mostly deal with reacting flows and mass transfer phemomenoes.
