Main project: A Comprehensive Study of Turbulent Natural Convection in a Pool heated from Below with an Evaporating Free Surface
Funding: BEL-V
Supervisor(s): Miltiadis Papalexandris

The PhD focuses on turbulent natural convection, thermal mixing and evaporation from the free surface of a Spent Fuel Pool (SFP) undergoing a Loss of Coolant (or Loss of Cooling) Accident (LOCA).

The aim is to better understand the physical phenomena via a series of large-eddy and direct numerical simulations. Simulation results will then be validated against experimental results measuring bulk and surface temperature measurements on a simplified geometry.
