On the Prediction of Unsteady Forces on Gas Turbine Blades: Part 2—Analysis of the Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article investigates the generation of unsteady forces on turbine blades due to potential-flow interaction and viscous-wake interaction from upstream blade rows. A computer program is used ...
Discussion: “Prediction of Unsteady Rotor-Surface Pressure and Heat Transfer From Wake Passings” (Tran, L. T., and Taulbee, D. B., 1992, ASME J. Turbomach., 114, pp. 807–817)
Publisher: The American Society of Mechanical Engineers (ASME)
Hierarchical Development of Three Direct-Design Methods for Two-Dimensional Axial-Turbomachinery Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The direct and inverse blade-design iterations for the selection of isolated airfoils and gas turbine blade cascades are enormously reduced if the initial blade shape has performance characteristics ...
On the Prediction of Unsteady Forces on Gas Turbine Blades: Part 1—Description of the Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article investigates the generation of unsteady forces on turbine blades due to potential-flow interaction and viscous-wake interaction from upstream blade rows. A computer program is used ...
Prescribed-Curvature-Distribution Airfoils for the Preliminary Geometric Design of Axial-Turbomachinery Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blade surfaces with continuous curvature and continuous slope of curvature minimize the possibility of flow separation, lead to improved blade designs, and reduce the direct and inverse blade-design ...
On the Propagation of Viscous Wakes and Potential Flow in Axial-Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the propagation of pressure disturbances due to potential-flow interaction and viscous-wake interaction from upstream blade rows in axial-turbine-blade rotor cascades. Results ...
Surface-Curvature-Distribution Effects on Turbine-Cascade Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The manufacturing accuracy of turbine blades is judged by the difference between the designed and produced location of each point around the airfoils. This paper shows that the design-point and ...
Off-Design Performance of Various Gas-Turbine Cycle and Shaft Configurations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design-point performance of various gas turbine cycles such as simple, regenerative, and intercooled-regenerative, is well understood. It is also understood that more elaborate shaft arrangements ...
Investigation of the Part-Load Performance of Two 1.12 MW Regenerative Marine Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regenerative and intercooled-regenerative gas turbine engines with low pressure ratio have significant efficiency advantages over traditional aero-derivative engines of higher pressure ratios, and ...
Models for Predicting the Performance of Brayton-Cycle Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbine performance is the result of choices of type of cycle, cycle temperature ratio, pressure ratio, cooling flows, and component losses. The output is usually given as efficiency (thermal, ...
