论文摘要
我们预测气体位移后从不同形的棱镜通道中回收的液体的体积。这种恢复因子在很大程度上取决于气体界面符合通道壁的接触角。我们表明，根据信道的形状将接触角度缩放为恢复因子的主曲线。}我们使用表面Evolver的数值模拟由毛细管进入压力的理论计算支持，该通道中具有三角形或矩形横截面或界面形状的毛细管进入压力，并在“三角形”中clyed canders can cander can cander can in trian cand cen triand cen triand cen in triangular cen triand cen in trian cen in triane cenlind。
We predict the volume of liquid recovered from different-shaped prismatic channels following gas displacement. This recovery factor depends strongly on the contact angle at which the gas-liquid interfaces meet the walls of the channel. We show that scaling the contact angle by a critical value, dependent on the channel shape, leads to a master curve for the recovery factor.} Our numerical simulations with the Surface Evolver are supported by theoretical calculations for the capillary entry pressure in a channel with a triangular or rectangular cross-section and for the interface shape in a "scalloped" triangular channel formed between three parallel cylinders.
