RISDesign Concept for Large Output Graz Cycle Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The introduction of closed cycle gas turbines with their capability of retaining combustion generated CO2 can offer a valuable contribution to the Kyoto goal and to future power generation. ...
The Effect of Rotor Tip Clearance Size onto the Separated Flow Through a Super-Aggressive S-Shaped Intermediate Turbine Duct Downstream of a Transonic Turbine Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The demand for a further increased bypass ratio of aero engines will lead to low pressure turbines with larger diameters, which rotate at a lower speed. Therefore, it is necessary to guide ...
The Application of Low-Profile Vortex Generators in an Intermediate Turbine Diffuser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The demand of further increased bypass ratios for turbofan engines will lead to low pressure turbines with larger diameter and lower rotational speed in conventional high-bypass aeroengine ...
Investigation of Vortex Shedding and Wake-Wake Interaction in a Transonic Turbine Stage Using Laser-Doppler-Velocimetry and Particle-Image-Velocimetry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current paper presents a time-resolved experimental flow investigation in a highly loaded transonic gas turbine stage operating continuously under engine representative conditions. The measurement ...
Shorten the Intermediate Turbine Duct Length by Applying an Integrated Concept
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The demand of further increased bypass ratio of aero engines will lead to low pressure turbines with larger diameters, which rotate at lower speed. Therefore, it is necessary to guide the ...
The Effect of Vane Clocking on the Unsteady Flow Field in a One-and-a-Half Stage Transonic Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current paper presents the results of numerical and experimental clocking investigations performed in a high-pressure transonic turbine with a downstream vane row. The objective was a detailed ...
Experimental Investigations of Clocking in a One-and-a-Half-Stage Transonic Turbine Using Laser Doppler Velocimetry and a Fast Response Aerodynamic Pressure Probe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current paper presents experimental clocking investigations of the flow field in midspan in a high-pressure transonic turbine with a downstream vane row (1.5 stage machine). Laser-Doppler-velocimetry ...
