Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Optimization on Scheduling for Cleaning Heat Exchangers in the Heat Exchanger Networks

open access: yesChemical Engineering Transactions, 2015
In the process at a plant that incorporating heat integration for energy recovery, fouling or formation of deposits on the heat exchanger often causes operational problems in production. Increasing the energy consumption resulted in higher operating expenses. Expenses can be reduced if the cleaning is done on a regular basis. Therefore, how to schedule
