Modelling of mixed thermodynamic model based on new materials

In order to solve the problem of performance mixed alkane phase change energy storage materials, this paper proposes modelling research thermodynamic model based on new materials. paper, binary system is studied, influence transition temperature, enthalpy and its composition explored, solid-liquid diagram drawn. We used different models predict temperature in melting process alkanes, which were mutually verified with experimental results. The results show that C9-C10 C9-C11 systems exhibit eutectic behavior. components are 88% (mass fraction, rest same) C9-12% C10 90% C9-10% C11. temperatures 218.25 K 215.15 K, respectively. C8-C9 has peritectic phenomenon, C10-C11 shows complete mutual solubility, their mini?mum points 200.25 234.35 Conclusion suitable for low materials range 210-220 providing data reference application storage.
