One‐Dimensional View of the Structural Changes in the Filtering Layer during Continuous Dust Deposition – A New Approach to a Holistic View of the Filtration Process

Chemie Ingenieur Technik, Volume 96, Issue 8, Page 1131-1137, August 2024.
The overall filtration process is viewed as a continuous change in the structure of the active deposition zone of a given filter layer: from the initial clean filter medium, via continuous particle deposition, to a new, dynamically preserved stable porous structure.

A Simplified Approach for Calculating Heat Transfer Coefficients for Fluid Guiding Elements with Alternating Redirections of Flow

Chemie Ingenieur Technik, Volume 96, Issue 8, Page 1116-1122, August 2024.
This article presents a simplified approach for calculating heat transfer coefficients of fluid guiding elements in tubular heat exchangers. Two models are implemented, validated, and compared. An empirical correlation is derived, and a characteristic number is proposed to estimate a correction factor for deviations caused by radial temperature ...

Experimental Heat Transfer Coefficients for Zeotropic Mixture Condensation of Hexamethyldisiloxane/Octamethyltrisiloxane and Ethanol/Hexamethyldisiloxane

Chemie Ingenieur Technik, Volume 96, Issue 8, Page 1123-1130, August 2024.
Experimental data is presented for mixture condensation within a wide composition range. Different aspects in the heat transfer deterioration of mixtures are discussed. The results serve to develop a novel superposition approach for the approximate calculation of mixture condensation heat transfer coefficients.
