Calculation of Three-Dimensional Unsteady Flows in Turbomachinery Using the Linearized Harmonic Euler Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An efficient three-dimensional Euler analysis of unsteady flows in turbomachinery is presented. The unsteady flow is modeled as the sum of a steady or mean flow field plus a harmonically varying ...
The Influence of Neighboring Blade Rows on the Unsteady Aerodynamic Response of Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present an analysis of the unsteady aerodynamic response of cascades due to incident gusts (the forced response problem) or blade vibration (the flutter problem) when the ...
1997 Best Paper Award—Structures and Dynamics Committee: A Coupled Mode Analysis of Unsteady Multistage Flows in Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational method is presented for predicting the unsteady aerodynamic response of a vibrating blade row that is part of a multistage turbomachine. Most current unsteady aerodynamic theories ...
Optimization and Mechanisms of Mistuning in Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An inverse design procedure has been developed for the optimum mistuning of a high bypass ratio shroudless fan. The fan is modeled as a cascade of blades, each with a single torsional degree ...
A Linearized Euler Analysis of Unsteady Transonic Flows in Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational method for efficiently predicting unsteady transonic flows in two-and three-dimensional cascades is presented. The unsteady flow is modeled using a linearized Euler analysis whereby ...
A Reduced Order Model of Unsteady Flows in Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel technique for computing unsteady flows about turbomachinery cascades is presented. Starting with a frequency domain CFD description of unsteady aerodynamic flows, we form a large, sparse, ...
