摘要
当二甲醚(DME)运用于柴油机时,准确了解二甲醚的热物理特性,将有助于对二甲醚的喷射和燃烧过程开展数值模拟。对二甲醚的饱和蒸汽压、液体粘度、弹性模量、汽化潜热、表面张力、热传导和扩散系数等热物理参数与温度或压力的关系式进行了比较和分析,可为数值模拟提供精确的参考依据。
The correct understanding of thermophysical properties of dimethyl ether (DME) will contribute to doing numerical simulation for the fuel injection and process of combustion, when the conventional fuel engine burns the dimethyl ether. The relationship between the vapor pressure ,liquid viscosity,density,bulk modulus,latent heat,surface tension etc with temperature and pressure was compared and analyzed, in order to find some reasonable and feasible equations, which offered references for numerical simulation.
