CV
Biography
- Mohammad Rahiminejad is working at the BFH as a Research Associate to address the fluid mechanics/heat transfer/building physics problems raised in various industrial projects using an interdisciplinary approach by undertaking numerical analyses, CFD simulations, and experimental measurements.
Mohammad holds a Ph.D. in Mechanics from EPFL. He has a multidisciplinary background ranging in various fields including Sustainable Energy Performance of Buildings, Ventilation in Underground Tunnels and Subway Platforms, Nanofluid materials, and Bio-fluid mechanics.
In his Ph.D. thesis, he investigated the impact of the ventilated air-space behind traditional and BIPV façades on the thermo-hydrodynamic performance of building wall structures.
Before starting his Ph.D., he worked on research/industrial projects to apprise decisions on the design of air conditioning systems in underground intercity/subway tunnels and platforms using CFD simulations.
He has also worked on a research project in his Master's thesis on water purification through graphene membrane using Molecular Dynamics (MD) simulations.
During his Bachelor's degree, for the first time, he worked on a novel research question to address the aerodynamic analysis of airflow in the human upper airway during sneezing using CFD simulations.
