Cavitation in an Axial Piston Pump

open access: yesBulletin of JSME, 1983
In an axial piston pump made of acrylic resin, cavitation is observed by the naked eye with a strobo-scope and by high speed photography, and the pressure changes in the cylinder are measured. The cavitation is classified into the following two groups ; one, related to the trapping phenomenon, can be prevented by a suitable design of valve plates ...

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

open access: yesAdvanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.
