The axial droplet velocity profile is nearly linear across the pipe section, and is different from the axial gas velocity profile. 液滴速度與氣相速度分布不同，在垂直方向上液滴的軸向速度近乎呈線(xiàn)性分布。
In addition, an axial velocity is observed at the windward stagnant point because of the guidance of the spiral fins, which is essentially distinct from bare tubes. 實(shí)驗數據表明，螺旋翅片的導流作用使得迎風(fēng)面的滯點(diǎn)處產(chǎn)生了軸向速度，這和光管有著(zhù)本質(zhì)的區別。
