... blades. This simple straight vane configuration was simulated and analyzed in different velocities. Its results are used later on for the comparison purpose. Recently, many patents are presented by using a special shape of a curved vane (Fig. 1b b ) claiming to support an enhanced thermal...

...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...
