RISOn Kinematic Relaxation and Deposition of Water Droplets in the Last Stages of Low Pressure Steam Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the first part of the paper steady twophase flow predictions have been performed for the last stage of a model steam turbine to examine the influence of drag between condensed fog droplets and the continuous vapor phase. ...
Two Phase Flow Modeling and Measurements in Low Pressure Turbines—Part II: Turbine Wetness Measurement and Comparison to Computational Fluid Dynamics Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The correct computation of steam subcooling, subsequent formation of nuclei and finally droplet growth is the basic prerequisite for a quantitative assessment of the wetness losses incurred in steam turbines due to thermal ...
Two Phase Flow Modeling and Measurements in Low Pressure Turbines—Part I: Numerical Validation of Wet Steam Models and Turbine Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this publication, an overview of the current state of wetness modeling at the Institute of Thermal Turbomachinery and Machinery Laboratory (ITSM) is given. For the modeling, an Euler–Euler method implemented in the ...
