Dr. Persoons’ Thermal Fluids Lab conducts research on experimental, numerical and theoretical modelling and analysis of fluid mechanics, heat transfer, aeroacoustics and energy management.

Our research activities cover several disciplines ranging from energy system technologies, electronics and photonics thermal management, dissolution in pharmaceutical systems, to fundamental research in thermal energy transport and active flow control.

This covers a wide range of scales, from large-scale systems (e.g., data centre cooling, energy system integration) to micro-scale thermal fluid devices (e.g., using impinging liquid, air, mist, swirl, pulsating and synthetic jets), as well as multi-physics phenomena including electro/magneto-hydrodynamics, two-phase flow, nano/micro-scale surface enhancements, thermoelectric energy harvesting and heat pipe technology.
