Asymmetric Supply Type Hydrostatic Journal Gas Bearings to Support Large Load Rotors

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Rotating machinerys have problems at bearings to support a rotor such as seismic ACROSS transmitters. The ACROSS ( Accurately Controlled Routinely Operated Signal System ) is a new technical method to detect subtle changes in the physical state of Earth ...

Dynamic pore water pressure in saturated soil due to turbine engine’s vibration [PDF]

open access: yesE3S Web of Conferences, 2023
The turbine engine that is operating will generate vibrations that are transmitted by the foundation into the soil layer. This causes the pore water pressure in the soil to increase, which causes the shear strength of the soil to decrease and can reduce ...

Feasibility Analysis of Adopting the Hydrogen Hydrostatic Thrust Bearing

open access: yesApplied Sciences, 2023
The hydrogen hydrostatic thrust bearing (HHTB) is a key component of hydrogen liquefaction that impacts turbo-expander characteristics. To analyze the feasibility of using the HHTB in this application, characteristics of HHTBs were calculated using a CFD

Mathematical Model of the Decomposition of Unstable Gas Hydrate Accumulations in the Cryolithozone

open access: yesGeosciences, 2022
We present a generalization of the mathematical model of gas discharge from frozen rocks containing gas-saturated ice and gas hydrates in a metastable state (due to the self-preservation effect) caused by the drop in external stress associated with ...

Rock physics model for velocity—pressure relations and its application to shale pore pressure estimation

open access: yesPetroleum Exploration and Development, 2023
Acoustic wave velocity has been commonly utilized to predict subsurface geopressure using empirical relations. Acoustic wave velocity is, however, affected by many factors. To estimate pore pressure accurately, we here propose to use elastic rock physics

Hydrostatic Asymmetric Journal Gas Barings for Seismic ACROSS Transmitters

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2007
The ACROSS (Accurately Controlled Routinely Operated Signal System) is used to detect subtle changes in the physical state of Earth's structure. The signal is sinusoidal elastic waves generated by the rotation of a rotor with eccentric mass set in ...
