Application Areas of Ionic Hydraulic Fluids
Chemical Engineering &Technology, Volume 46, Issue 1, Page 14-20, January 2023., 2023 Ionic liquids as high‐tech technical fluids have also made their way into the field of hydraulic drives. With excellent lubricating properties, a wide temperature range, low pour point and vapor pressure, as well as nonflammability and environmental suitability, problems with only one type of fluid, namely, an ionic hydraulic fluid, instead of using ...

Wear assessment model for cylinder liner of internal combustion engine under fuzzy uncertainty
Mechanics & Industry, 2021 The wear of the piston ring-cylinder system is inevitable in the operation of the internal combustion engines (ICEs). If wear exceeds the maximum, the piston ring-cylinder system will be failure.

Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023 In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Experiments and Computational Fluid Dynamics on Vapor and Gas Cavitation for Oil Hydraulics
Chemical Engineering &Technology, Volume 46, Issue 1, Page 147-157, January 2023., 2023 A computational fluid dynamics cavitation model for vapor and gas cavitation in hydraulic oil is presented, parameterized, and validated. For numerous operating points, cavitation in a realistic valve geometry is visualized using shadowgraphs and high‐speed cameras. Vapor and gas cavitation are experimentally separated by complete degassing of the oil.

Development of Hydrogen-Free Diamond-Like Carbon Coating for Piston Rings
Tribology Online, 2017 The first piston ring application of a hydrogen-free diamond-like carbon (H-free DLC) coating to a mass-production gasoline engine reduces friction. It is found that the friction reduction effect between the cylinder bore and piston is 18%.

Casimir interaction: pistons and cavity [PDF]
J.Phys.A41:164007,2008, 2007 The energy of a perfectly conducting rectangular cavity is studied by making use of pistons' interactions. The exact solution for a 3D perfectly conducting piston with an arbitrary cross section is being discussed.

Energy and velocity of a forming vortex ring [PDF]
, 2000 It is known that vortex rings formed by large stroke ratios (in a piston/cylinder arrangement) pinch off from their generating jets at a fairly constant universal time scale.
