Give an example.(BNU–Nov'95)Ans: When a system has only heat and work transfer, but there is no mass transfer, it iscalled as closed system.Example: Piston and cylinder arrangement.4. Define a open system, Give an example.Ans: When a system has both mass and energytransfer it is ...
3.3.1. Energy Density During the cyclic loading and unloading process, assuming that there was no energy exchange between the machine and the external environment, the test equipment transferred energy to the sample through mechanical work, part of which was converted into elastic energy stored insid...

Elastocaloric cooling is an emerging cooling technology. This work develops a ternary TiNiCu alloy based elastocaloric prototype using a roller-driven mechanism for partial kinetic energy recovery. The prototype achieved a 125% improvement in the material coefficient of performance and a 78% work recove...
Previous work has focused on truss networks and anisotropic honeycombs, neither of which can achieve this theoretical limit. We find that stiff but well distributed networks of plates are required to transfer loads efficiently between neighbouring members. The resulting low-density mechanical metamaterials...
