The Aerodynamic Mixing Effect of Discrete Cooling Jets With Mainstream Flow on a Highly Loaded Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the application of film cooling to turbine blades, experimental investigations were performed on the mixing processes in the near-hole region with a row of holes on the suction suction ...
The Influence of Inlet Swirl Distortions on the Performance of a Jet Propulsion Two-Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aeroengine intakes containing S-shaped diffusers produce different types of inlet swirl distortions and essentially a combination of a twin swirl and a bulk swirl. The main object of this ...
A Numerical Study of the Influence of Grid Refinement and Turbulence Modeling on the Flow Inside a Highly Loaded Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thorough numerical study was conducted to simulate the flow field inside a highly loaded linear turbine cascade. The numerical investigation was focused on the secondary flow field as well ...
The Influence of Load Distribution on Secondary Flow in Straight Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an experimental study of the three-dimensional flow within two highly loaded turbine cascades subjected to the same overall load but different load distributions. Data were ...
Performance Improvements of Compressor Cascades by Controlling the Profile and Sidewall Boundary Layers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For increasing the thrust-to-weight ratio of modern turbojet engines, the number of stages of the turbo components or at least the number of blades per stage must be minimized. This inevitably ...
Controlling the Secondary Flow in a Turbine Cascade by Three-Dimensional Airfoil Design and Endwall Contouring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A highly loaded turbine cascade has been redesigned with the objective to reduce the secondary flow by applying endwall contouring and three-dimensional airfoil design in the endwall regions. ...
Influence of Free-Stream Turbulence and Blade Pressure Gradient on Boundary Layer and Loss Behavior of Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The optimization of the blade surface velocity distribution is promising for a reduction of turbine cascade losses. Theoretical and experimental investigations on three turbine cascades with the ...
