About Me:

I completed my Master's Degree in Computational Mechanics from the University of Duisburg-Essen in 2016. During my master thesis, I worked on analysis of real gas model for compressible flows. I also spent a year in Aix-Marseille University, France in 2018 where I was working in numerical modeling in fluid-structure interaction using volume penalization method as a student assistant. Since September 2019, I started working as a Project Assistant and a PhD student at the Institute of Particle and Process Engineering under the EC-funded Horizon 2020 “Marie Curie” Innovative Training Network (MSCA-ITN) “MATHEGRAM” Project.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 812638

Research Interest:

The aim of my present research is to investigate the thermo-mechanical behaviour of granular materials at high consolidation stresses. This can be achieved by considering the continuum approach (e.g. FEM, FVM) that models the detailed mechanical response. I am using "foam-extend" (an extended version of OpenFOAM which uses finite volume method) for updating and developing libraries for contact analysis. This will not only allow me to predict the behaviour of particle deformation but also practicable to couple thermal stresses with an objective to quantify and characterize the heat generation or the energy dissipated due to the contribution from inter-particle friction as well as the particle itself generating heat due to plastic deformation. Subsequently, I will continue with the novel validation which counts for the individual grain deformation against the conventional assumption where bulk is considered as continuum as well as with other discrete approaches.
