AIChE Journal, Volume 69, Issue 4, April 2023., 2023 Abstract A three‐dimensional eigenspace appears in the analysis of an ellipsoid immersed in quadratic ambient viscous flow fields. To celebrate the mathematical achievements of Babatunde Ogunnaike, we focus on mathematical details of the eigenvalues and eigenfunctions of the double‐layer operator that appears in the integral representation of velocity ...

Highly accurate special quadrature methods for Stokesian particle suspensions in confined geometries
International Journal for Numerical Methods in Fluids, Volume 93, Issue 7, Page 2175-2224, July 2021., 2021 We present a highly accurate boundary integral method for simulation of rigid particles in three‐dimensional periodic Stokes flow with confining walls. Our method includes a special quadrature method based on upsampled quadrature and quadrature by expansion, accelerated using a precomputation scheme.

Advances in Tribology, Volume 2018, Issue 1, 2018., 2018 Mixed lubrication between a given pair of surfaces is directly related to the parameter ηu/p. Any change in microgeometry produces a shift in the transition between the boundary and lubricated regimes. Using an asperity based model including five families of asperities (2 for full fluid lubrication and 3 for local boundary lubrication), we simulate ...

Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017 To investigate the influence of surface features, in the form of pits, on the wear resistance of grey cast iron (GCI), a finite element model of the pin‐on‐disc friction system, with pits distributed in a curved radial direction, was developed using APDL programming and the tribological behavior of textured surfaces was studied.

Comparison of the Influences of Surface Texture and Boundary Slip on Tribological Performances
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 Close attentions have been widely paid to the engineering textured and slip surfaces for improving bearing tribological performances. Comparison studies on the tribological characteristics of slip and textured surfaces are carried out in this work. The analysis results point out that the influences of surface texture and boundary slip on tribological ...

Biosurface and Biotribology, Volume 10, Issue 4, Page 143-158, November 2024.Abstract The purpose of this research is to develop data‐driven machine learning (ML) models capable of estimating the specific wear rate of ultra‐high molecular weight polyethylene (UHMWPE) used in hip replacement implants. The results of the data‐driven models are demonstrating a high level of consistency with the experimental findings acquired from ...

Tribological Performance of Laser‐Based Surface Textured Nonconformal Contacts
Advances in Tribology, Volume 2024, Issue 1, 2024.The benefits of surface textures on rolling and sliding tribological contacts have been an exciting field of study over the last three decades. Laser surface texturing (LST) is a comparatively newer texturing methodology that yields repeatable precise microtextures.
