... characteristics significantly. Before discussing the new design, a reference model is taken as the base line for comparison. Straight vanes, Fig. 1b b , are widely used as the ventilation blades. This simple straight vane configuration was simulated and analyzed in different velocities. Its results...

...Akhilesh P. Rallabandi; Yao-Hsien Liu; Je-Chin Han The heat transfer characteristics of a rotating pin-fin roughened wedge-shaped channel have been studied. The model incorporates ejection through slots machined on the narrower end of the wedge, simulating a rotor blade trailing edge. The copper...

... of the first stage of vanes and blades of the gas turbine. The study takes place in a three-dimensional model in steady state using FLUENT ® 6.3.26, applying the k-ε turbulence model and chemical equilibrium to the combustion process. The results show the influence of the transition piece geometry over...

...E. I. Esposito; S. V. Ekkad; Yong Kim; Partha Dutta Impinging jets are commonly used to enhance heat transfer in modern gas turbine engines. Impinging jets used in turbine blade cooling typically operate at lower Reynolds numbers in the range of 10,000–20,000. In combustor liner cooling...

... gas stream in a gas turbine. Even if the temperature limits remain about the same, the expansion in a hydrogen turbine will have to proceed with a greater enthalpy drop, and therefore require larger number of stages. This also implies that the flow areas may need to be expanded, and the blade span...
