摘要
本文提出了研究圆管分层层流流动的新模型，并利用该模型研究了圆管分层流动速度分布规律，得出了速度场解析表达式，最后，研究了分层流动的阻力规律，为分层掺气减阻提供了理论依据．算例表明。
A new model of stratified laminar flow in pipe is proposed and the velocity distribution laws of stratified flow in pipe are studied. The analytical correlation of velocity field is obtained by using this model. The flow resistance law of stratified flow is investigated. The results provide the theoretical base of drag reduction by aeration in stratified flow. The calculating results show that aeration in stratified flow can achieve effective drag reduction.
