A COMPREHENSIVE VALIDATION OF CFD-BASED WET STEAM APPROACH FOR THE MODELLING OF STEAM EJECTORS

open access: yesProceeding of 8th Thermal and Fluids Engineering Conference (TFEC), 2023
Ejector-based system performance is closely related to the complex fluid-dynamic behavior inside ejectors, which is usually optimized through CFD simulations. The rapid expansion in ejector’s primary nozzle leads to the condensation of the working fluid, and since it strongly affects system performance, it has to be properly accounted.

Dielectric properties of wet steam based on a double relaxation time model

open access: yesThe European Physical Journal E, 2019
The last stages of most steam turbines operate in wet steam, resulting in water erosion of the rotor blades and the reduction of turbine efficiency. Accurate measurement of steam wetness is the key to ensure an efficient and stable operation of steam turbines.

The search for an appropriate condensation model to simulate wet steam transonic flows

International Journal of Numerical Methods for Heat and Fluid Flow, 2023
Purpose The purpose of this study is to model steam condensing flows through steam turbine blades and find the most suitable condensation model to predict the condensation phenomenon. Design/methodology/approach To find the most suitable condensation model, five nucleation equations and four droplet growth equations are combined, and 20 cases are ...

A metastable wet steam turbine stage model [PDF]

open access: yesNuclear Engineering and Design, 2002
A model for the prediction of the efficiency of axial flow steam turbine stage is described, where the flow through turbine cascade is considered non-homogeneous and metastable. At the exit an oblique shock brings it to equilibrium. The losses in the cascade are expressed according to Dunham and Came (Trans. ASME (1970)) and Kacker and Okapuu (J.

Two-fluid model for prediction of wet steam transonic flow

International Journal of Heat and Mass Transfer, 2013
Summary The paper presents a description of a two-fluid slip velocity model dedicated to the steam condensing flow modeling. The model solves separate flow governing equations for the compressible, viscous and turbulent vapor phase, and for the compressible and inviscid liquid phase.
