Abstract: Feedheating in steam turbines, the use of steam extracted from the turbine to heat the feedwater, is known to raise the plant efficiency and so is included in most steam turbine power plant designs. The steam is extracted ...

Abstract: The first vane leading edge film cooling is challenging because of the highest thermal load and the complex flow interaction between the hot mainstream gas and the coolant flow. This interaction varies significantly from ...

Abstract: The flow at the combustor turbine interface of power generation gas turbines with can combustors is characterized by high and nonuniform turbulence levels, lengthscales, and residual swirl. These complexities have a ...

Abstract: This paper presents a numerical study of the impact of tip gap uncertainties in a multistage turbine. It is well known that the rotor gap can change the gas turbine efficiency, but the impact of the random variation of the ...
