Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced 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 ...

A mathematical model of fluid flow in a scraped-surface heat exchanger
, 2007 A simple mathematical model of fluid flow in a common type of scraped-surface heat exchanger in which the gaps between the blades and the device walls are narrow, so that a lubrication-theory description of the flow is valid, is presented.

Fundamentals of Heat Exchangers
, 2018 Heat exchangers are used to transfer heat between two sources. The term exchanger applies to allequipment used to transfer heat between two streams. However, the term is commonly used to equipment inwhich two process streams exchange heat with each other. This research paper explains the basics of heatexchangers, covering such topics as: classification;

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
