Parametric Analysis of Oscillating Squeeze Film Using a New Dimensionless Parameter
Abstract: A comprehensive mathematical model has been established including a new dimensionless parameter Ω to investigate the effects of surface roughness and permeability of rubber block on leakage flow rate and hydrodynamic force generated in fluid film between annular porous rubber block and oscillating annular rigid block. The modified Reynolds equation, Laplace equation and governing equation for three-parameter viscoelastic model are solved simultaneously to obtain pressure developed in fluid film between …

On the Role of Surface Roughness in Ankle Joint Replacements
Abstract: AbstractResearch efforts in biomechanics have geared towards the long-term effectiveness andsurvival of total joint replacements, because of osteoarthritis causes loosening, instability,wear of articulating components and finally loss of function. Surface roughness of articulatingcomponents significantly influences their tribological behavior. Other factors affecting thewear of articulating surfaces include material and geometrical properties. In this work, thehuman ankle joint is represented by an equivalent ellipsoid-on-plane model to study the effectof surface roughness on …

Interfacial and Tribo-Mechanical Performance of a TiO₂–Castor Oil Polymeric Nanofluid During Sustainable Machining of AISI 316L Stainless Steel Under MQL Conditions
Abstract: This research examines the tribo-mechanical performance and interfacial film characteristics of a TiO₂-reinforced castor-oil polymeric nanofluid during the turning of AISI 316L stainless steel under minimum-quantity lubrication (MQL). A Taguchi L9 orthogonal array was utilized to assess the synergistic effects of cutting speed, depth of cut, and coolant composition on surface integrity, while machining experiments were performed under dry, conventional, and TiO₂-nanofluid lubrication techniques. ANOVA and multiple-regression modeling were used …
