Chapter 1 Introduction 1.1 Preliminary Remarks When you think about it, almost everything on this planet either is a fluid or moves within or near a fluid. -Frank M. White What is a fluid?

Boundary layer(边界层) Although frictional effects in slightly viscous fluid are indeed present, they are confined to a thin layer near the surface of the body, and the rest of the flow can be considered inviscid. (1904, Prandt/)

When is a flow compressible? compressible flow differs from an incompressible one in that significant change happens in the density

Properties of Pressure Vertical to the surface and point into it. At any point, pressure is independent of orientation

[3-11单组元流体的热力学基本关系式有哪些? [3-2]本章讨论了温度、压力对H、S的影响,为什么没有讨论对U的影响?

一、是否题 1.纯物质由蒸汽变成固体,必须经过液相。 (错。可以直接变成固体。 2.纯物质由蒸汽变成液体,必须经过冷凝的相变化过程。 (错。可以通过超临界流体区。) 3.当压力大于临界压力时,纯物质就以液态存在 (错。若温度也大于临界温度时,则是超临界流体。 4.纯物质的饱和液体的摩尔体积随着温度升高而增大饱和蒸汽的摩尔体积随着温度的升高而减 小。 (对。由则纯物质的TV相图上的饱和汽体系和饱和液体系曲线可知。)
