标题： Effect of bubble deformability on the vertical channel bubbly flow

摘要： 本文描述了流体动力学视频：“气泡可变形性对垂直通道气泡流动的影响”。 使用直接数值模拟研究了气泡可变形性对湍流垂直通道中气泡上升流动速率的影响。 一系列气泡可变形性逐渐降低的模拟显示，流动从中间均匀分布的可变形气泡流动突然转变为几乎球形气泡、壁面峰值分布且流动速率显著降低的流动。 显示英文摘要

摘要： This article describes the fluid dynamics video: "Effect of bubble deformability on the vertical channel bubbly flow". The effect of bubble deformability on the flow rate of bubbly upflow in a turbulent vertical channel is examined using direct numerical simulations. A series of simulations with bubbles of decreasing deformability reveals a sharp transition from a flow with deformable bubbles uniformly distributed in the middle of the channel to a flow with nearly spherical bubbles with a wall-peak bubble distribution and a much lower flow rate.
