There are two ways that the solid particles come from : ( 1 ) environment and wear particles ; ( 2 ) solid additives suspending in carrier fluids 固体颗粒主要来自两个方面:一是外界环境和磨损的产物;二是固体悬浮添加剂。
( 2 ) solid additives suspending in carrier fluids . interactions between the particles , liquids and the frictional surfaces will greatly affect the performances of the tribopairs 此时固体颗粒与润滑油的作用、固体颗粒与摩擦副表面的作用等对摩擦副的性能均产生重要的影响。
Liquids are divided into single and complex fluids according to theirs structure . complex fluids are called soft materials too . electrorhological fluids compose of high dielectric constant particles and lower dielectric constant carrier fluids 电流变液是一种典型的软物质,通常是由高介电常数的微小颗粒分散在低介电常数的绝缘液体中形成的悬浮体系。
By performing fourier transformation , the relationship between the turbulent intensity of the particle and that of the carrier fluid was obtained which makes clear that particle size , specific gravity , velocity gradient , and the characteristic frequency of energy - containing eddies are four basic influencing parameters . it is proven theoretically that under certain conditions , the stream - wise and transverse particle turbulent intensities exceed those of the carrier fluid . based on the equations of two - phase flow , the presence of fine sediment suspension is shown to attenuate the turbulent intensity of the water 通过对细小颗粒在剪切流场中运动方程的fourier分析,得到了颗粒脉动强度和流体脉动强度之间的定量关系,表明颗粒粒径、颗粒密度、流速梯度以及紊动场含能旋涡的特征频率是影响颗粒脉动强度的主要因素,首次从理论上证明了在一定条件下,颗粒在纵、垂向的脉动强度均会超过相应的流体脉动强度,为已有的实测资料提供了合理的解释。
