RISUnsteady Flow and Aeroelasticity Behavior of Aeroengine Core Compressors During Rotating Stall and Surge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper will focus on two core-compressor instabilities, namely, rotating stall and surge. Using a 3D viscous time-accurate flow representation, the front bladerows of a core compressor were ...
Simplified Modal Pushover Analysis to Estimate First- and Higher-Mode Force Demands for Design of Strongback-Braced Frames
Publisher: ASCE
Abstract: Strongback-braced frames employ an essentially elastic truss, or strongback, that defines an elastic load path to redistribute seismic demands and mitigate the formation of story mechanisms. However, unlike the forces from ...
Multibladerow Forced Response Modeling in Axial-Flow Core Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the formulation and application of an advanced numerical model for the simulation of blade-passing and low-engine order forced response in turbomachinery core compressors. The ...
Fragility and Recovery Models for Energy, Water, and Wastewater Systems for Seismic Regional Risk and Resilience Assessment: State-of-the-Art Review and Database
Publisher: ASCE
Abstract: Fragility functions and recovery models are often used to assess lifeline systems subjected to extreme hazards. However, even though many databases for fragility and recovery models exist for essential buildings and ...
