Thermo-hydro-dynamic investigation of journal bearing by a two dimensional model [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
Journal bearings are widely used in industrial machinery, working under heavy loading and high rotating velocity. These bearings are interfered sometimes with sever thermal damages. So the prediction of their exact working temperature is necessary.

Ketogenic Diet as an Epigenetic Therapy in SETD1B‐Related Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Histone lysine methyltransferases such as SETD1B regulate chromatin structure and gene transcription. Ketone bodies, including butyrate, act as histone deacetylase inhibitors. We report a 4‐year‐old boy with SETD1B‐related absence epilepsy, refractory to conventional medications, who achieved sustained > 90% seizure reduction on the Modified ...

Oil film analysis and axial uniform distribution optimization for the sliding bearing in GTF engines

open access: yesXibei Gongye Daxue Xuebao
The journal bearings of planetary gear are the key technologies of the gearbox in geared turbo fan engine(GTF). GTF journal bearings are usually operated under high-speed, heavy-load, and large-eccentricity conditions.

Numerical investigation of static characteristic of a tilting-pad journal bearing using shear stress transport model and air backflow

open access: yesAdvances in Mechanical Engineering, 2019
Numerical simulations are important in bearing designs and should be in accordance with real working conditions. Two details are analyzed for the numerical simulations with a three-dimensional model of a large tilting-pad journal bearing included.

Performance Analysis of Couple Stress Fluid Operated Elastic Hydrodynamic Journal Bearing

open access: yesTribology Online, 2019
Performance of bearings used in modern machinery is significantly affected by the elasticity of the bearing liner and viscosity of the lubricant. This paper considers couple stress fluid (CSF) model of the lubricant along with elasticity of bearing liner.
