RISTime-Transformation Simulation of a 1.5 Stage Transonic Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time-accurate transient blade row (TBR) simulation approaches are required when there is a close flow coupling between the blade rows, and for fundamentally transient flow phenomena such as aeromechanical analysis. Transient ...
Experimental and Computational Analysis of a Multistage Axial Compressor Including Stall Prediction by Steady and Transient CFD Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Siemens Energy has commissioned an extensive multiyear experimental and numerical (computational fluid dynamics (CFD)) project to improve its ability to design for and predict compressor stall. The experimental test rig ...
Computational Fluid Dynamics Modeling of Low Pressure Steam Turbine Radial Diffuser Flow by Using a Novel Multiple Mixing Plane Based Coupling—Simulation and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The diffuser and exhaust of low pressure steam turbines show significant impact on the overall turbine performance. The amount of recovered enthalpy leads to a considerable increase of the turbine power output, and therefore ...
Mistuned Forced Response Predictions of an Embedded Rotor in a Multistage Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper covers a comprehensive forced response analysis conducted on a multistage compressor and compared with the largest forced response experimental data set ever obtained in the field. The steadystate aerodynamic ...
