摘要
流体热物性是流体热物理性质的简称,包括流体的热力学性质和迁移(输运)性质,其中热力学性质主要包括PVT性质、饱和蒸气压、临界参数、饱和气液相密度、比热容、表面张力、声速和混合物的相平衡性质等,而迁移性质则主要包括粘度、导热系数和扩散系数等。实践证明,可靠的热物性数据不仅是许多工程设计和科学研究,特别是动力工程和化学工程中的工业流程设计不可缺少的,而且往往与基础研究的创新紧密联系在一起。
Thermodynamic and transport properties of fluids are generally called thermophysical properties. Thermody-namic properties include PVT property, vapor pressure, critical parameters, saturated vapor and liquid densities, heat capacity, surface tension and speed of sound and vapor - liquid - equilibrium ( VLE) for mixtures. Transport properties include viscosity, thermal conductivity, and diffusion coefficient etc. The reliable thermophysical property data not only are necessary for engineering design and scientific research, especially in power engineering and chemical engineering, but also closely combine with the innovation of basic research.
