摘要

考虑了液体膜和湍流气体在狭窄垂直通道中的逆流流动。在小雷诺数条件下，在一定的流动参数条件下，该问题可简化为研究膜厚偏离无扰动水平的一个演化积分微分方程。对周期扰动的演化进行了数值研究。给出了模型方程的几种解。

WAVES AT THE INTERFACE WITH COUNTERCURRENT FLOW OF A THIN LIQUID FILM AND TURBULENT GAS IN A NARROW VERTICAL CHANNEL

A countercurrent flow of a liquid film and a turbulent gas in a narrow vertical channel is considered. In the case of small Reynolds numbers and under certain conditions of the flow parameters, the problem is reduced to studying one evolutionary integrodifferential equation for the deviation of film thickness from an unperturbed level. Evolution of periodic disturbances is numerically studied. Several solutions to the model equation are presented.
