A Fourier transform based data reduction method for the evaluation of the local convective heat transfer coefficient

open access: yes, 2004
A new data reduction technique for measuring the convective heat transfer coefficient is reported. The technique is based on the evaluation of the Fourier transform of simultaneously measured free stream temperature and surface wall temperature or ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

open access: yesChemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Transient thermal modelling of green anode cooling in the aluminium industry

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before
