Steam reheater with helical tube bundle for wet steam turbine [PDF]
E3S Web of Conferences, 2020 Since steam heat exchangers, used at steam cycle of Russian nuclear power stations, were designed while the knowledge about the separation and the heat exchange processes was limited, deviations between its empirical and theoretical characteristics occur.

Transonic Flow of Wet Steam — Numerical Simulation
Acta Polytechnica, 2012 The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper formulation of the problem consists

Wet steam measurement techniques [PDF]
Reviews in Chemical Engineering, 2018 Abstract In recent years a greater need for power station efficiency has become evident; improving turbine blade efficiency is one of the methods proposed. This efficiency depends upon the wetness of the steam that comes into contact with the blades of the low-pressure turbine stage in general and all turbines in nuclear power generation.
