Chemical Engineering &Technology, Volume 46, Issue 1, Page 95-101, January 2023., 2023 The bulk shear and wall slip of a confined nonpolar lubricant, a complex branched‐hydrocarbon oil, were studied using molecular dynamics simulation. Different temperatures and molecular masses were investigated for a Couette flow. As the number of branches of the liquid molecule increases, the shear stresses and the wall slip increase.

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.

Elastohydrodynamic Simulation of Pneumatic Sealing Friction Considering 3D Surface Topography
Chemical Engineering &Technology, Volume 46, Issue 1, Page 167-174, January 2023., 2023 The influence of the surface topography of the sealing counterface in a pneumatic spool valve on the sealing friction force during operation is investigated. For that, the 3D surface topography of the running surface has been measured optically. Using an elastohydrodynamic lubrication simulation, it could be demonstrated that the surface topography ...
