Capillary pinching in a pinched microchannel [PDF]
, 2007 We report a study of the capillary pinching of a gas bubble by a wetting liquid inside a pinched channel. The capillary pinching induces very reproducible bubbling, at a very well-defined frequency.

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Study of lubricant jet flow phenomena in spur gears: Out of mesh condition [PDF]
, 1983 The penetration depth onto the tooth flank of a jet of oil at different velocities pointed at the pitch line on the outgoing side of mesh was determined. The analysis determines the impingement depth for both the gear and the pinion.

Tribology Transactions, 2023 This study presents a theoretical analysis to quantify power losses generated by an oil-jet lubricated deep groove ball bearing. Loaded rolling elements (RE) have been thoroughly studied in the past for the Elasto Hydrodynamic Lubricated (EHL) regime, while a wellknown problem concerning rolling element bearing (REB) power losses is the estimation of ...

Large-bore tapered-roller bearing performance and endurance to 2.4 million DN [PDF]
, 1983 The operating characteristics and experimental life estimates for 120.65 mm bore tapered roller bearings of two designs under combined radial and thrust loads were determined. A modified standard bearing design was tested at speeds up to 15,000 rpm.

3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency
Advanced Materials Technologies, EarlyView.A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.
