On the basis of piv measurement of the gas solid velocity field, the size and the numbers of particles are measured by newly developed image processing software. the results are identical with the variation of the factual size of particles. by the viable datum, the average size of particles in the cross section is calculated in the dilute phase area of circulating fluidized beds ( cfb ) riser
在piv測速系統基礎上，通過二次開發的圖像識別軟體，實現不同工況下各截面顆粒粒徑分佈的測量，測量結果基本反映出實際顆粒粒徑變化，證明了該方法的可行性，進一步獲得了循環流化床稀相區顆粒粒徑分佈特性。 -
The solids holdup is lower in the center than in the wall region at the radial positions, and the solids holdup is higher in the lower section than in the upper section of the riser
在徑向分佈上，顆粒濃度呈現中心稀，邊壁濃的狀態。在軸向上，顆粒濃度呈現上稀下濃的分佈。 -
It is also found that the flow developments in all radial locations are not synchronized, but it extended gradually from the core region to the wall, until finally a fully developed flow is achieved across the whole cross - section of the riser. the flow development at the annulus region near the wall, as a control process of the whole flow development in the riser, is much slower, and more sensitive to the change of operation conditions than that at the core region
氣固兩相流動沿徑向的發展並不同步，而是一個由核心區向邊壁區逐漸擴展，最終達到充分發展的過程，該過程主要受邊壁區發展過程式控制制；相對于核心區，邊壁區的發展不僅顯著緩慢，而且受操作條件的影響也較顯著。 -
In a square - section desulfurizing csb, in order to overcome the defects mentioned above and to improve the desulfurization efficiency, the wedge - type internals were symmetrically mounted at the middle of the height of the riser
今在過去實驗的基礎上，利用方形截面床內構件簡單易實現的優點，在床中部安裝對稱構件，考察對稱內構件對兩相流動行為的影響。
