RISImpact of Surface Roughness and Coning on Hydrodynamic Face Seals During an Idling Process of Main Coolant Pump in Mixed Lubrication Regime
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydrodynamic face seal of the main coolant pump (MCP) of a nuclear power plant operates under hydrodynamic lubrication. At low idle speed, the seal faces may touch, transitioning the lubrication regime from hydrodynamic ...
Identification of the Velocity, Thickness, and Interfacial Roughness of Coating Using Full Time-Domain URCPS: Cross-Correlation-Based Inverse Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aiming at characterizing interfacial roughness of thin coatings with unknown sound velocity and thickness, we derive a full time-domain ultrasonic reflection coefficient phase spectrum (URCPS) as a function of interfacial ...
