Title: Two-phase steam flow in turbines and separators: theory, instrumentation, engineering

Book ·
OSTI ID:5358369

A collection of the edited lecture notes for a course on two-phase flow in turbines presented at the von Darman Institute for Fluid Dynamics in May 1974 is presented. The lectures are intended mainly for students, scientists, and practicing engineers involved in design, development, research, and operation of turbine plants. The chapters on condensation processes and gas dynamics of wet steam should, however, be useful in a general way for all researchers working in the domain of two-phase flows. The term ''wet-steam'' refers to a two-phase mixture in which the liquid phase is dispersed in various forms. In a continuous vapor medium the water formed by partial condensation of the steam appears in the low-pressure part of large turbines and also in the high-pressure part of nuclear turbines for water-cooled reactor systems. Its presence is marked by a reduction in thermodynamic efficiency and by various problems of erosion and corrosion. These and other aspects are described from the basic fundamentals of the condensation process to the latest operating experience with modern turbines. The sever chapters, include information on basic concepts; gas dynamics of wet steam and energy losses in wet-steam turbines; condensation in flowing steam; instrumentation for wet steam; experimental wet steam turbines; operating experience with wet steam turbines; and external water separators.
