Dataset for: History effects on the gas exchange between a bubble and a liquid

History effect will occur when bubble surface concentration changes during the mass transfer between bubble and ambient liquid. In order to estimate the history effect in bubble diffusion process, the project uses numerical simulation to study the significance of history effect in three situations: (1)determine pressure oscillation threshold in rectified diffusion (2)change lifetime of dissolution and growth for a single component bubble in ambient liquid, when surface tension is non-negligible (3) change the dissolution rate for a multi-component bubble. The dataset primarily summarizes the results of the first case, as the history effect turned out to be most significant in the first one.

当气泡与周围液相之间发生传质过程且气泡表面浓度发生变化时，将产生历史效应（History effect）。为了评估气泡扩散过程中的历史效应，本项目采用数值模拟方法，针对三类场景探究历史效应的影响显著性：(1) 确定整流扩散（rectified diffusion）中的压力振荡阈值；(2) 当表面张力不可忽略时，环境液相中单组分气泡的溶解与生长寿命的变化情况；(3) 多组分气泡的溶解速率的变化情况。本数据集主要汇总第一类场景的研究结果，因历史效应在该场景下的影响最为显著。
