Over mij

I am a PDEng student, working on the design of optimum flow conditions for spray drying of milk in a vortex chamber.

In 2011, I obtained my BSc degree in Chemical Engineering from University of the Punjab, Pakistan. In 2015, I completed my MSc degree in Chemical and Energy Engineering at the Otto von Guericke University, Germany. The master thesis topic was based on a numerical study of penetration depth for different fuels (methane, biogas, methanol) in a PFR (Parallel Flow Regenerative) shaft kiln.

My research is on the design and optimization of air flow and spray conditions for milk in a lab scale vortex chamber spray dryer. The high temperature and high-G acceleration in vortex chamber intensifies the heat, mass and momentum transfer. This leads to reduction in investment costs, energy savings, operational flexibility and product innovation.

This research focuses on developing a CFD model that provides insights to the complex multiphase flow inside the dryer. The model can then be used to design experiments and provide scale up rules.
