Performance tests with a 4.75 inch bore tapered-roller bearings at high speeds [PDF]

The tapered-roller bearings were tested at speeds to 15,000 rpm which results in a cone-rib tangential velocity of 130 m/sec. (25,500 ft/min). Lubrication was applied either by jets or directly to the cone-rib, augmented with jets.

Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...

Bioconvective Chemically Reactive Radiative Squeezing Flow of a Casson Hybrid Nanofluid Between Two Parallel Plates Under Variable Viscosity

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybrid nanofluids, known for their superior thermal and electrical conductivity, have demonstrated remarkable potential in enhancing the heat transfer capability of conventional base fluids. This study analyzes the effects of viscous dissipation and heat radiation on two‐dimensional unsteady incompressible squeezing flow transporting hybrid ...
