1、第一章1、流体定义受任何微小切力都会产生连续变形(流动)的物质。2、流体承受的作用力流体承受的力主要为压力,流动的流体可以承受切力。3、流体特性:易流动性及粘性。4、流体质点的概念流体质点就是流体中宏观尺寸非常小而微观尺寸又足够大的任意一个物理实体,也称流体微团。5、流体质点具有四层含义:(1)宏观尺寸非常小;(2)微观尺寸足够大;(3)是包含有足够多分子的一个物理实体;(4)形状可以任意划分。6、连续介质的概念:把流体视为由无数连续分布的流体微团所组成的连续介质,这就是流体的连续介质假设。8、粘性的概念:流体运动时内部产生切应力的性质叫作流体的粘性。9、粘性产生的原因:分子间的相互引力;分子

3、连续介质、无粘性和不可压缩性第 2 章流体静力学1、作用在流体上的力质量力(重力、惯性力)、表面力(法向力、切向力)2、静压力特性:方向性、等值性4、等压面及选取流体中压强相等的点组成的面叫等压面。等压面的选取:(1)同种流体;2)静止;3)连续。5、静压强基本公式7、静压强的计算单位帕斯卡、液柱高单位、大气压单位10、物体浸在液体中的位置(1)沉体;(2)潜体;(3)浮体。第三章流体动力学基础1、研究流体流动的方法拉格朗日法、欧拉法。2、定常流动(恒定流动):运动参数只是坐标的函数,而不是时间的函数。非定常流动:流动参量随时间变化的流动3、在不可压缩流体中流线皆为平行直线的流动为均匀流。4、

4、均匀流具有下列性质1)各质点的流速相互平行,有效断面为一平面;2)位于同一流线上的各个质点速度相等;3)沿流程各有效断面上流速分布相同,但同一有效断面上各点的流速并不相等;4)各质点的迁移加速度皆为零,如流动是均匀的、定常流动,那么各质点的加速度为零;5)有效断面上压强分布规律与静止流体相同;特别地,对于重力场中不可压缩流体,过流断面上满足5、缓变流和急变流流线不是严格平行,但流线之间夹角很小,或流线的曲率半径很大,或两者皆有,这种流动称为 缓变流,其有效断面称为缓变流断面。在缓变流断面上可以认为流线近似平行,有效断面为一平面,压强分布近似与静止流体相同。CgpZ那种流线不平行,加速度较大的流
