About me

Hey there!

As a research scientist at the Professorship of Technical Thermodynamics, Technische Universität Bergakademie Freiberg, Germany, my experties lies in the fields of heat and mass transfer, multiphase flows, numerical methods, code development, Computational Thermo-Fluid Dynamics (CTFD) simulations and automated post-processing solutions.

Over the past years, I've gained valuable experience in numerical simulation using the open-source Finite Volume Method (FVM) based Computational Fluid Dynamics (CFD) software OpenFOAM®.

Soon after joining this institute, I found myself gravitating towards IT administration. I owe a great deal of thanks to my supervisor Dr.-Ing. Ingo Riehl, for his unwavering support and guidance in both the fields (i.e., CTFD and IT administration).

In my free time, I enjoy administering my home cloud server and learning the art of web hosting. I am particularly passionate about developing simple, robust and cost-effective home cloud solutions.

Note:

This website is still a work in progress and I plan to add more content (on CFD simulations, post-processing techniques, Openmediavault, Nextcloud, Raspberry Pi, etc.) in the coming days, SO STAY TUNED!!!.
