Contact Interaction of Steam Turbine Inner Casing Elements During Plastic Deformation

Contact Pressure Validation of Steam Turbine Casing for Static Loading Condition

Steam Turbines are devices used to convert thermal energy of steam into mechanical energy, which may be used to produce Electrical Energy. Steam turbine generator units are being used extensively all over the world for generation of electric power and for co-generation of steam and power. Contact pressure and pretension in bolts-analysis has been made easier in recent years due to the availabil...

Steam Turbine Steam System

Steam Turbine Configuration

Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...

Steam turbine model

In order to characterize the transient dynamics of steam turbines subsections, in this paper, nonlinear mathematical models are first developed based on the energy balance, thermodynamic principles and semi-empirical equations. Then, the related parameters of developed models are either determined by empirical relations or they are adjusted by applying genetic algorithms (GA) based on experimen...

Dissolving Equilibrium-Immiscible Elements via Severe Plastic Deformation*

Severe plastic deformation has the fascinating power of alloying equilibrium-immiscible elements, overriding the thermodynamic driving force (positive heat of mixing) that would dictate phase separation in equilibrium. This article briefly reviews the current understanding of this subject, in terms of experimental evidence for atomic-level alloying and phase selection, and in particular the mod...
