Research Expertise (University of Antwerp):Reducing the energy use in buildings is essential to reach carbon neutrality and combat the effects of climate change. Traditional energy systems in buildings, which mainly used fossil fuels such as natural gas and oil for heating, need to be replaced with renewable energy sources. For buildings, district heating and heat pumps are typically used as replacement for fossil fuel boilers. The refrigerants in these heat pumps can also contribute to global warming and new fluids are currently being researched and introduced. Two-phase flow and heat transfer occurs in the different components of heat pumps, but is still not well understood. Numerical CFD simulations of these phenomena have become feasible in recent years, which will drastically improve our fundamental knowledge. My research focuses on two tracks: numerical simulations of complex (two-phase) flow and heat transfer and dynamic modelling of building energy system components. In the first track computational fluid dynamics (CFD) simulations are use to analyze flow and heat transfer in different components such as heat exchangers, piping and ducts. The second track focuses on developing dynamic and accurate models of building energy components such as thermal energy storage systems, which are necessary for detailed building energy simulations, component sizing and control.
