Lubrication State Transformation and Characteristic Analysis of Sliding Bearing under Low Rotary Speed and High Eccentric

open access: yesJixie chuandong, 2022
Taking hydrodynamic sliding bearing as the research object,models of hydrodynamic lubrication and mixed lubrication are established. The characteristic parameters such as friction force,friction coefficient,load-carrying capacity and temperature rise of ...

Influence of hydrodynamics on many-particle diffusion in 2D colloidal suspensions

open access: yes, 2003
We study many-particle diffusion in 2D colloidal suspensions with full hydrodynamic interactions through a novel mesoscopic simulation technique. We focus on the behaviour of the effective scaled tracer and collective diffusion coefficients $D_T(\rho ...

Refinement of Norrbin Model via Correlations between Dimensionless Cross-Flow Coefficient and Hydrodynamic Derivatives

open access: yesJournal of Marine Science and Engineering
To develop a simplified and highly accurate ship motion model, this study thoroughly investigated the relationship between the dimensionless cross-flow coefficient and the four hydrodynamic derivatives of the Norrbin model. Eight different types of ships

Numerical Simulation of the Lubrication Performance of the Stator and Rotor Friction Pair Surface Rhombus-like Texture in Screw Pumps

open access: yesLubricants
To address wear failure in screw pump stator and rotor friction pairs, this study constructed a numerical model of a rhombus-like micro-dimple texture on friction pair surfaces based on the scale structure of rhombus rattlesnakes.
