RISLeakage and Rotordynamic Force Coefficients of a Labyrinth Seal and a Pocket Damper Seal Operating With Wet Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Subsea centrifugal compressors commonly using labyrinth seals (LS) and pocket damper seals (PDS) must withstand the flow of oil in gas mixtures with a liquid volume fraction (LVF) up to 5%. This paper presents experimental ...
The Hexapodopter: A Hybrid Flying Hexapod—Holonomic Flying Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This document introduces the holonomic flying capabilities of the Hexapodopter, a six-legged walking machine capable of vertical take-off and landing. For ground locomotion, each limb has two degrees-of-freedom (2DoF); ...
A Stepped Shaft Labyrinth Seal Verses A Pocket Damper Seal: Leakage and Dynamic Force Coefficients Under Wet Gas Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern turbomachinery favors pocket damper seals (PDS) which produce more effective damping than labyrinth seals (LS). Liquid tolerant compressors enable deep sea oil and gas (O&G) facilities; and seals supplied with ...
