Thermal stress is one of major causes of cracking in high-temperature components of gas turbines. This paper presents a thermo-structural analysis of cracks on the vane of a gas turbine for power generation. The vane components include three airfoils with hub and shroud sections. The airfoils have serpentine-type internal passages and film cooling holes on the pressure-side surfaces for cooling. The...
Local acceptance of wind energy technology has become an important factor to consider when designing local and national wind energy technological innovation policies. Previous studies have investigated the factors that shape the local acceptance of wind power in high-income countries. However, to the best of our knowledge, these factors had not been investigated in China. Utilizing a survey and quantitative...
Detailed heat/mass transfer coefficients and film-cooling effectiveness were measured on the tip and inner rim surfaces of a blade with a squealer rim. The test blade was a two-dimensional version of a modern first-stage gas turbine rotor blade with a squealer rim. The experimental apparatus was equipped with a linear cascade of three blades, and the axial chord length (C x ) was 237 mm with...
To design an impingement/effusion cooling system that realizes the lowest thermal stress in an impingement/effusion cooling system, we conducted thermal analysis and optimization using a second-order response surface method. The optimal impinging jet system was based on four design variables: the spacing between the impinging jets and effusion holes (1.0 ≤ Sp ≤ 5.0), the channel height from impinging...
The efficiency of micro gas turbine generator is affected significantly by the temperature level in the micro gas turbine system. If the operation temperature of generator and compressor increases, the efficiency of generator and compressor decreases, greatly. This study investigates the heat transfer and temperature distribution in a micro gas turbine system. In addition, the temperature levels on...
This work investigates the hydrogen generation via methanol thermal decomposition (TD) over the three group IA alkali metals, Na, K, and Cs, incorporated into aluminosilicate catalysts (IA–AlxSiyOz). The scanning electron microscopy (SEM) images of the IA–AlxSiyOz catalysts revealed various and regular morphologies such as cube (Na), bouquet (K), and spherical (Cs), but the other two catalysts, K-alumina...
