چکیده

• Non-bonded regenerator with first order particles was successfully tested for one year. regenerators can stably improve cooling performance. The material is stabilized without causing significant performance degradation. Reduced flow resistance in non-bonded yields lower friction factors. aim of this study to develop more stable magnetocaloric regenerators, made from non-epoxy-bonded La(Fe,Mn,Si) 13 H y address the instability issues conventional a first-order phase transition. materials are obtained by increasing α − Fe content at expense small reduction adiabatic temperature change. However, experimental results show that structure improves efficiency and reduces pressure drop, potentially compensating material’s effect. Compared epoxy-bonded exhibit larger span (10.2 K no load) specific power (27% improvement 4 K). Due elimination epoxy, factor higher packing density obtained. long-term mechanical chemical stabilities verified comparing heat, effectiveness, drop before after test period than

Experimental study of random-close-packed colloidal particles.

A collection of spherical particles can be packed tightly together into an amorphous packing known as "random close packing" (RCP). This structure is of interest as a model for the arrangement of molecules in simple liquids and glasses, as well as the arrangement of particles in sand piles. We use confocal microscopy to study the arrangement of colloidal particles in an experimentally realized ...

Behavior of Packed Bed Thermal Storage

A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...
