Comprehensive throughflow method for steam turbine development
… measurements. However, condensation in steam turbines is much more complex and optical measurements show a much broader droplet spectrum than in nozzles and steady cascade expansions. The dominant theory explaining this behaviour is that large-scale fluctuations in static temperature …

Aerodynamics of Low Pressure Steam Turbine Exhaust Systems
… avenue for improving the performance of large steam turbines. For this reason, LP exhaust systems have attracted the attention of the research community for decades. Nevertheless, we still lack understanding of the flow physics and loss mechanisms in the exhaust system, especially at part-load …

Development of appropriate steam turbine models in Flownex
… this goal. The development of appropriate steam turbine models in Flownex supports fulfilment of this goal. Steam turbines of fossil and nuclear power plants make up most of the generating capacity for the majority of industrialised and industrial developing countries, except for those …

Numerical Loss Prediction of high Pressure Steam Turbine airfoils
Steam turbines are widely used in various industrial applications, primarily for power extraction. However, deviation for operating design conditions is a frequent occurrence for such machines, and therefore, understanding their performance at off design conditions is critical to ensure that the …

On Aerothermal Optimization of Low-Pressure Steam Turbine Exhaust System
… in the aerothermal optimization of Low-Pressure Steam Turbine Exhaust System (LPES). The first one is the high computational cost due to the complexity of LPES geometry. To make things worse, designers have to consider extra cost caused by change of constraints, multi-objective and …

The effect of metals on the deterioration of steam-turbine oils
… effect of several metals on the deterioration of steam-turbine oils. A special test apparatus was constructed and three commercial turbine oils were tested in the presence of 14 different metal and metal combination. Included in this group of metals were five bearing metals, several metals now …

Investigation of Aerodynamic Profile Losses for a Low-Reaction Steam Turbine Blade
… and near-tip sections of a low-reaction steam turbine blade and compares them to CFD of the former. The purpose of these tests was the refinement of a proprietary empirical profile loss model. A review of the literature shows that experimental data on this type of blade is not openly …

Effects of Mach Number and Flow Incidence on Aerodynamic Losses of Steam Turbine Blades
… the aerodynamic losses of two high-pressure steam turbine nozzles (526A, 525B) subjected to a large range of incident angle and exit Mach number. The blades were tested in a 2D transonic windtunnel. The exit Mach number ranged from 0.60 to 1.15 and the incidence was varied from -34o to 35o. …

Conceptual Design and Instrumentation Study for a 2-D, Linear, Wet Steam Turbine Cascade Facility
The design of last stage low pressure steam (LP) turbines has become increasingly complicated as turbine manufacturers have pushed for larger and more efficient turbines. The tip sections of these LP turbines encounter condensing wet steam at high velocities resulting in increased losses. These …
