Two-phase flow in engineering systems related to energy

Lecturer(s): Mikhail GOROKHOVSKI, Mathieu CREYSSELS
Course ⋅ 24 hTC ⋅ 8 h


To understand the fundamental physics of a two-phase flow, including interface instability, droplets breakup, dispersion, evaporation, droplets or coal particles combustion. To introduce the modeling of such flows and to consider numerous applications in energy production processes.


Two-phase flows, interface and instabilities, atomization and spray formation, particle-fluide interactions and dynamics, spray combustion, coal and biomass combustion


This course is an attempt to provide the essential physics of two-phase flows in the context of energy production processes. Scope : i) Spray production and dispersion of particles. The gas-liquid interface. Evaporation. ii) Combustion in two-phase flows (coal particles and sprays) ; industrial burners. iii) Heat-and-mass transfert in the presence of phase transition ; water-cooled reactors and boilers
