Analysis of Two-Phase Flow in Nozzles and Turbine Buckets.

Abstract

A one-dimensional analytical study was made of the two-phase flow of wet steam in a convergent-divergent nozzle with negligible wall friction. The liquid phase is assumed to consist of a cloud of spherical droplets, whose size is either controlled by a critical Weber number or predetermined. Nozzle geometry, phase velocities, mass flux density and local efficiencies are determined by numerical integration from the basic differential equation. The two-dimensional two-phase flow in impulse turbine buckets was also investigated. The parameters that control the deviation angle of the droplets from the gas path are identified. (Author)
