Dynamic Performance of Organic Rankine Cycle Driven by Fluctuant Industrial Waste Heat for Building Power Supply

Energies, 2023
Organic Rankine cycle (ORC) is widely used to recover low-grade waste heat. The effects of heat-source temperature amplitude and period on ORC systems are discussed based on operating parameters and power-generation performance.

The superheated Melting of Grain Boundary [PDF]

, 2005
Based on a model of the melting of Grain Boundary (GB), we discuss the possibility of the existence of superheated GB state. A Molecular Dynamics simulation presented here shows that the superheated GB state can realized in the high symmetric tilt GB ...

Simulation of the macrosegregation in the gear steel billet continuous casting process

工程科学学报, 2021
Macrosegregation forms due to relative motion between liquid and solid phases on the macro scale during solidification. As macrosegregation is formed during a solidification process, it is difficult to remove it in the subsequent rolling and heat ...

How high the temperature of a liquid be raised without boiling?

, 2000
How high the temperature of a liquid be raised beyond its boiling point without vaporizing (known as the limit of superheat) is an interesting subject of investigation. A new method of finding the limit of superheat of liquids is presented here.

Analysis of acoustic emission during the melting of embedded indium particles in an aluminum matrix: a study of plastic strain accommodation during phase transformation

, 2012
Acoustic emission is used here to study melting and solidification of embedded indium particles in the size range of 0.2 to 3 um in diameter and to show that dislocation generation occurs in the aluminum matrix to accommodate a 2.5% volume change.
