Research presentation

Abolfazl Hayati

Senior lecturer

Research subject: Energy systems

Abolfazl Hayati has PhD in Energy system and indoor environment (2017) from University of Gävle (HiG). He has MSc in Energy system (2012) from HiG and BSc in Mechanical Engineering (2009) from Tehran Polytechnic.

Dr Abolfazl Hayati has been involved in research at University of Gävle both during the PhD studies as a part of ”Spara och bevara” (Save and preserve) project (Dnr 2011-002440) assigned by Swedish Energy Agency, and after graduation as assistant professor. His research is about district heating and cooling systems, building energy systems, energy efficiency, indoor climate, environmental assessment of buildings, natural ventilation, city ventilation and solar energy. The investigations include measurements (in laboratory, field and wind tunnel), analytical modelling and numerical simulations using IDA Indoor Climate and Energy (IDA-ICE) and CFD simulation with ANSYS Fluent.

As senior lecturer, Abolfazl has been course responsible and lecturer for a number of courses at Energy system study programs at University of Gävle, and has been involved in supervising Master and Bachelor students (Link to the supervised thesis) and co-supervising PhD students since 2017.
