structure of turbulence中文什么意思
例句與用法
- It begins by analyzing turbulent pipe flow to know about the structure of turbulence ; then it precedes to make a general impression of the velocity and concentration distribution in two - phase pipe flows based on complex findings of the predecessors , mainly digesting and retaining their essence . finally , it proposes the method and formulas of calculating the flow resistance of sewage in pipe viewing from the point of two - phase flows , which are associated with empirical equations used in practice at present
首先，對(duì)管道內(nèi)的紊流進(jìn)行分析，以了解紊流的結(jié)構(gòu)；然后對(duì)前人大量紛繁復(fù)雜的液-固兩相流動(dòng)研究成果進(jìn)行整理和取舍，以便對(duì)污水在管道內(nèi)流動(dòng)的流速分布和濃度分布狀況有一個(gè)總體的把握；最后結(jié)合目前工程上采用的液-固、氣-固兩相流動(dòng)阻力計(jì)算的經(jīng)驗(yàn)公式，根據(jù)相似理論，提出了從兩相流動(dòng)的角度計(jì)算污水在管道內(nèi)流動(dòng)阻力的方法和公式。 - For dilute solid - liquid two - phase flow , the mechanism of particle motion driven by fluid is the main subject , especially the particle motion in the near wall region . the bursting phenomenon and coherent structure of turbulence play an important role on the motion of particles in the near wall region
明槽紊流近壁區(qū)的顆粒運(yùn)動(dòng)與紊動(dòng)猝發(fā)現(xiàn)象及紊流相干結(jié)構(gòu)有著密切的關(guān)系，開展近壁區(qū)顆粒與紊流相互作用的機(jī)理研究對(duì)于流體力學(xué)和泥沙運(yùn)動(dòng)力學(xué)都有著重要的理論意義和實(shí)際價(jià)值。
