Comparisons of two different grid systems in the simulation of oscillatory flow field in a baffled reactor 兩種網(wǎng)格在振蕩流反應(yīng)器三維流場計算中的比較
The experiment was carried out in two situations , without net flow and with net flow . the influence of oscillatory flow reynolds number ( re0 ) and strouhal number ( si ) to the injection dispersion performance of ofm was explored 實驗分無凈流量和有一定凈流量兩種情形,探討了振蕩雷諾數(shù)re _ o 、斯特勞準(zhǔn)數(shù)st對振蕩流場中的注入分散特性的作用以及凈流雷諾re _ n的影響情況。
In this paper the injection dispersion in an oscillatory flow mixer has been studied by using the flow visualization technique with a solution of blue dye as the tracer . the process of injection dispersion was monitored with a digital camera connecting to a computer that treated the video data stream synchronously to obtain the attenuation curve of relative deviation of the flow image ' s gray scale values 實驗采用以藍(lán)色有機(jī)染料為示蹤劑的流動顯形技術(shù),由攝像頭實時攝取注入分散過程的動態(tài)圖像,計算機(jī)同步分析視頻流數(shù)據(jù),從而以在線監(jiān)測的方式獲得流場圖像的灰度相對方差隨時間衰減的曲線。
