Air bubble guide for adequacy of ophthalmic viscosurgical device during phacoemulsification [PDF]
Indian Journal of OphthalmologyPhacoemulsification in hard cataracts is a challenge. The use of dispersive ophthalmic viscosurgical devices (OVDs) to protect the endothelium is a routine step in such scenarios.

Investigation of the Role of Body Shape on an Air Lubrication System Inspired by Penguins [PDF]
BiomimeticsBubble-assisted drag reduction is a promising strategy for improving the energy efficiency of underwater bodies, but its effectiveness depends not only on air injection but also on the ability of the body geometry to retain bubbles close to the surface ...

ANALYSIS OF AIR-BUBBLE PLUMES [PDF]
Coastal Engineering Proceedings, 1974 Models are developed to describe the gross behavior of air-bubble plumes generated by point and line sources of air-bubbles released in stagnant water bodies of uniform density. The models predict plume width, velocities, and induced flow rates as a function of elevation above the source.

The Fluidization Backwash Method of Filter Beds by Air-water Bubbly Flow
Journal of Water and Environment Technology, 2020 A novel fluidization backwash method by the air-water bubbly flow with air bubbles of various sizes has been proposed for rapid filters. The backwash efficiency is closely related to the bubble wake motion.
