inlet velocity profile 中文意思是什麼
inlet velocity profile
解釋
進口速度分布圖-
The research results show that compared with the uniform inlet velocity profile, the exponential inlet velocity profile has more advantages to get lower contaminant concentration, to prevent patient and operating apparatus in the operating area from infection by airborne disease germs and to reduce the airflow rate needed for pollutant concentration control
研究表明，與通常採用的均勻風速的送風口相比，變化風速的送風口對于降低手術室工作細菌濃度，防止病人手術切口及手術器械等回風氣流攜帶的浮遊細菌再次感染，以及減少手術室的送風量等方面具有明顯的優點。 -
The goal of this paper is to study fully developed turbulent pipe flow. with the aid of the tripping annulus at the inlet, based on the experimental investigation and numerical simulation, detailed researches on a few basic rules in pipe flow have been performed, such as mean velocity profile, relative intensity of turbulence, the log - law, von karman ' s constant and reattachment length, thus filling some gaps in the research work of predecessors and obtaining a far - reaching understanding
本文的目的就是利用入口擋環進一步探索充分發展的圓管湍流，通過實驗和數值模擬對圓管湍流的若干基本規律，如平均速度分佈、相對湍流強度、對數定律、馮?卡門常數和再附著長度等進行詳細的研究，以填補前人研究中的一些空白，並獲得更深入的了解。 -
Then by using the excel software, we get the figures of the velocity profile and pollution concentration distribution of different sections, and get the ventilation efficencies of the three ventilation forms. as view from the efficiency of the draining pollution, a desired ventilation is regarded as the up - inlet and down - outlet on the same side after compairing the three ventilation efficiency. the trend of the velocity profile and the pollution concentration distribution both are basically identical with the practice, and the numerical results of the ventilation efficency accord with the ones studied by prof
從排污效果的角度上來看，分析得出這幾種方式下較好的送排風方式是同側上送下排方式。從得到的流場、濃度場分佈的趨勢來看與實際大體一致，計算的通風效率與已經有的實驗值大體相吻合，說明本文所採用的數學模型合理，計算方法基本可靠。
