Problem 2 Fusion reactor blanket studies Heat
removal
Title Usage of Two-Phase systems (foam flows,
gravitational liquid films, dispersed liquid
droplets) for cooling of heated surfaces
Goals - to study the heat and mass transfer
processes during the contact of two-phase flows
with the heated surfaces - to
achieve high heat transfer efficiency using
reduced coolant mass flow and low energy
consumption. Recent publications   1. Gylys
