The liquid fraction of foam is an important quantity in engineering process control and
essential to interpret foam rheology. Established measurement tools for the liquid fraction of …

This work evaluates the addition of wash water to a foam fractionation cell in order to remove
the soluble impurities from a protein foam. Due to the irreversible adsorption of the proteins …

Liquid drainage through foam is dominated by gravity, capillary, and viscous forces. The
liquid is conducted by an isotropic network of Plateau borders; however, imposed stress …

The measurement of bubble sizes in aqueous foams based on images of the surface is a
typical method used in laboratory and industrial scales. In this article the relationship …

The diameter distribution of bubbles in foam is one of the most important features in foam-
based separation processes like foam fractionation and froth flotation. In this study the …

Hannes Emmerich studied mechatronics at the TU Dresden and received his Diploma in
2019. Since 2020, he is a research fellow with the laboratory for measurement and sensor …

Unwanted foam bears the risk of affecting different thermal industrial processes negatively,
by reduced process efficiency, contamination, and total shutdown. Mechanical defoaming …

Abstract At the Technische Hochschule Dresden, the predecessor institution of the TU
Dresden, a specialization “Engineer for Process Engineering” was established in 1953 with …

Liquid foams occur whether intentionally or unintentionally across different industrial sectors.
The detection of foam and characterization of liquid content currently requires complex …

Foam formation occurs for various substrates during distillation processes. A concrete
prediction of the foam formation can only be approximated due to the physical, chemical …
