The numerical simulations of bubble motion in dilute surfactant solutions reported previously by two of the authors contained a serious numerical inaccuracy. In agreement with experiments, single bubbles released from rest were predicted to reach a maximum speed before slowing to a terminal speed. However, subsequent experiments demonstrated that, in the simulations, the bubbles reached their terminal speed too quickly. The source of the discrepancy is an inaccuracy associated with the numerical algorithm used to solve the surfactant transport equation on the bubble surface. After correcting the problem, the simulations agree much better with the experiments.
两位作者之前报道的关于稀表面活性剂溶液中气泡运动的数值模拟存在严重的数值误差。与实验结果一致，预测从静止状态释放的单个气泡在减速至终端速度之前会达到最大速度。然而，随后的实验表明，在模拟中，气泡达到终端速度的速度太快。差异的根源在于用于求解气泡表面表面活性剂输运方程的数值算法存在误差。修正该问题后，模拟结果与实验结果的吻合度更高。
