The whole anthropogenic aluminum cycle consists of four stages: alumina and aluminum production......
J. Cent. South Univ. (2018) 25: 1464-1474 DOI: https://doi.org/10.1007/s11771-018-3840-6 Energy and exergy recovery from exhaust hot water using organic Rankine cycle and a retrofitted.... However, the excess heat carried by EHW is typically ignored and discharged into the environment, resulting in heat loss and heat pollution. An organic Rankine cycle (ORC) is an attractive technology......
J. Cent. South Univ. Technol. (2009) 16: 0339-0343 DOI: 10.1007/s11771-009-0057-8 Parameter fitting of constitutive model and FEM analysis of solder joint thermal cycle reliability for lead... data. Furthermore, the Anand model was used in the FEM analysis to evaluate solder joint thermal cycle reliability. The results show that solder Sn-3.5Ag has a better creep resistance than solder......
