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 ...

Unconditional energy stable IEQ-FEMs for the Cahn-Hilliard-Navier-Stokes equations [PDF]
arXivWe propose several unconditionally energy stable invariant energy quadratization (IEQ) finite element methods (FEMs) to solve the Cahn-Hilliard-Navier-Stokes (CHNS) equations. The time discretization of these IEQ-FEMs is based on the first- and second-order backward differentiation methods.
