Modeling of Crescent‐Type Internal Gear Pumps Considering Gear Radial Micromotion
Chemical Engineering &Technology, Volume 46, Issue 1, Page 128-136, January 2023., 2023 A numerical approach for investigating crescent‐type internal gear pumps, coupling a lumped parameter pressure solver with a CFD film simulator based on transient gap geometries solved from gear loading forces was proposed. Volumetric efficiency prediction was validated by measurements.

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.
