STABILITY CHARACTERISTICS AND CFD ANALYSIS OF TWO-PHASE FLOW OF OIL FILM JOURNAL BEARING HAVING TWO OIL FILLER HOLES

Stability characteristics and CFD analysis of two-phase flow of oil film journal bearing having two oil filler holes

In this paper, a new stabilization method which can control an oil whip utilizing the starved lubrication on small bore journal bearing is described.Oil Baby Toothpaste whip is one of the excited vibration that is caused by the action of oil film force of journal bearing.Therefore, it is very important to suppress the oil whip in the bearing design

Functional insights of novel Bathyarchaeia reveal metabolic versatility in their role in peatlands of the Peruvian Amazon

ABSTRACT The decomposition of soil organic carbon within tropical peatlands is influenced by the functional composition of the microbial community.In this study, building upon our previous work, we recovered a total of 28 metagenome-assembled genomes (MAGs) classified as Bathyarchaeia from the tropical peatlands of the Pastaza-Marañón Foreland Ba

Recrystallization of Cu-30Zn brass during friction stir welding

The recrystallization process of Cu-30Zn brass during friction stir welding (FSW) was investigated.The microstructural evolution in the stirring period and the subsequent normal air-cooling period were separately studied by using stop-action technology, liquid nitrogen cooling, and subsequent heat treatment.During the stirring period, Illustrated B

Studies on the propagation dynamics and source mechanism of quasi-monochromatic gravity waves observed over São Martinho da Serra (29° S, 53° W), Brazil

A total of 209 events of quasi-monochromatic atmospheric gravity waves (QMGWs) were acquired over 5 years of gravity waves (GWs) observation in southern Brazil.The observations were made by measuring the OH (hydroxyl radical) 127 emission using an all-sky imager hosted by the Southern Space Observatory (SSO) coordinated by the National Institute fo
