prof. M. Shahi (Mina)

I am leading the research line of heat conversion and storage at the TFE department. My research is focused on model-based analysis, design, and improvement of heat conversion and storage concepts and devices through the fundamental understanding of transport phenomena. Together with my team of PhD and postdoc students, we are striving to achieve 100% sustainable heating and cooling in buildings. Focus areas include magnetocaloric heat pumps/ refrigerators and heat storage based on PCMs/TCMs. Our approach is grounded on rigorous multiscale modeling and experimentation. My target applications are domestic heating and cooling and industrial waste heat recovery.

The overview of current research activities can be found in my group page:
