Book excerpt: Published experimental aerodynamic efficiency results were compared with results predicted from two published analytical methods. This is the second of two such comparisons. One of the analytical methods was used as published; the other was modified for certain cases of coolant discharge from the blade suction surface. The results show that for 23 cases of single row and multirow discharge covering coolant fractions from 0 to about 9 percent, the difference between the experimental and predicted results was no greater than about 1 percent in any case and less than 1/2 percent in most cases.

This book was released on 1978 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previously published experimental aerodynamic efficiency results for a film cooled turbine stator blade are compared with analytical results computed from two published analytical methods. One method was used as published; the other was modified for certain cases of coolant discharge from the blade suction surface. For coolant ejection from blade surface regions where the surface static pressures are higher than the blade exit pressure, both methods predict the experimental results quite well. However, for ejection from regions with surface static pressures lower than the blade exit pressure, both methods predict too small a change in efficiency. The modified method gives the better prediction.

Available in PDF, EPUB and Kindle. Book excerpt: This study is an investigation of the film cooling effectiveness and heat transfer coefficient of a two-dimensional turbine rotor blade in a linear transonic cascade. Experiments were performed in Virginia Tech's Cascade Wind Tunnel with an exit Mach number of 1.2 and an exit Reynolds number of 5 x 10 (exp 6) to simulate real engine flow conditions. The freestream and coolant flows were maintained at a total temperature ratio of 2 +0.4 and a total pressure ration of 1.04. The freestream turbulence was approximately 1%. There are six rows of staggered, discrete cooling holes on and near the leading edge of the blade in a showerhead configuration. Cooled air was used as the coolant. Experiments were performed with and without film cooling on the surface of the blade. The heat transfer coefficient was found to increase with the addition of film cooling an average of 14% overall and to a maximum of 26% at the first gauge location. The average film cooling effectiveness that suggest either a transition from a laminar to a turbulent film regime or the regime or the existence of three-dimensionality in the flow-field over the gauges.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving the film cooling technique provides more cooling capacity to withstand the harsh thermal environment in the next generation of gas turbines. A two-dimensional cascade has been designed and constructed in a subsonic wind tunnel in order to investigate the heat transfer of shaped holes over a gas turbine stator. An in-situ calibration technique has been developed to obtain the film cooling performance without disturbing the aerodynamic flow around the vane surface. Subsequently, the cooling performance of two types of shaped holes is measured at different positions over the entire surface. Firstly, a louver scheme was investigated on the convex surface of the suction side and on the concave surface of the pressure side. In addition, a proposed smooth expansion was investigated over the highly curved surface of the leading edge. The location of the hole has a high impact on the cooling performance due to the difference in curvature. The investigated blowing ratios slightly affect the cooling performance of the presented schemes due to the considerable reduction in the jet momentum that impedes the jet lift-off at exit. The shaped holes provide a higher net heat flux reduction compared with the similar cylindrical holes and other shaped holes in the literature. The contribution of this study will help to enhance the cooling performance in the next generation of gas turbines.
