The effect of air distributor on the flow fields was studied with emphasis . the working conditions of the bubble column simulated in the numerical study were as same as in the experiments . the velocity profile at axial direction showed a peek in the center , and a backward flow near the wall when usl / usg < 19 . 6 鼓泡塔內軸向液相速度的徑向分布呈塔中心峰值、壁面附近倒流形式,且與氣相折算速度大小有關,當液相折算速度一定時,隨氣相折算速度增大而愈加陡峭,返混也劇烈。

This is similar to another aluminium plate system shown below which is nearing completion at usl and is destined for a customer in china 該系統與另一個鋁板系統相似,該系統顯示在下面,且已在usl接近完成,最終客戶在中國

Forgive those who unintentionally hurt usl . do not be someone who is easily hurt by others 要原諒一個無心傷害人的人,不能做一個輕易被別人傷害的人。
