thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...

Many factors can influence the displacements of a dam, including water level variability and environmental temperatures, in addition to dam composition. In this work, optical-based classification, thermal diachronic analysis, quasi-PS (Persistent Scatter) Interferometric SAR technique have been applied determine both forcing resulting crest Castello (South Italy) over one-year time period. The ...

Transformers in power plants act as intermediaries between the power plant and the power grid, which are affected by electrical stresses such as switching, thermal stresses such as overload and arc, and chemical reactions in the dielectric oil. Acid and moisture components cause deterioration of transformer oil and paper insulation. Condition assessment of transformers is a method to predict an...

construction and operation of dams have two main effects on streams. at first it increases detention time and then leads to thermal stratification. changing of water quality is the result of these effects and the outflow has different physical, chemical and biological characteristics from inflow.in this study thermal regime in proposed bakhtyari reservoir was simulated with ce-qual-w2 model. th...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

For concrete, the appearance of temperature load due to hydration heat cementitious materials is inevitable and important structural safety dam. This paper investigates effect different surface insulation measures on thermal stress dam concrete by means finite element simulation calculation. The calculation results show that for lowering concrete. When equivalent coefficient transfer was less t...
