By applying the dimensional analysis approach to a lab-scale stirred tank process, the influence of process parameters on the foamability of three model surfactants: SLES, Tween 20 and Brij L23 is investigated and modelled. For validation of process law, the theoretical approach is complemented with an experimental work varying process parameters such as agitator rotational speed rate (N), mixing time (t_m) and bottom clearance (C_b). The foam rate of expansion of surfactant solutions is correlated with success to two dimensionless numbers: the Reynolds number and the mixing time number. Reynolds number is observed as mainly governing the amount of formed foam. A clear difference between the intermediate flow regime (Re < 10⁵) and the turbulent one (Re > 10⁵) is observed leading to a different process law for each regime. Master curves are finally drawn and can be used for helping to predict final foam volumes in the studied experimental domain according to both dimensionless numbers.

通过将尺寸分析方法应用于实验室规模的搅拌釜工艺，研究并模拟了工艺参数对三种模型表面活性剂（SLES，Tween 20和Brij L23）的发泡性的影响。为了验证过程定律，在理论方法上辅以改变过程参数的实验工作，例如搅拌器转速（N），混合时间（t _m）和底部间隙（C _b）。表面活性剂溶液的泡沫膨胀率与成功与两个无因次数相关：雷诺数和混合时间数。观察到雷诺数主要决定泡沫的形成量。中间流态（Re <10 ⁵）和湍流态（Re> 10）之间存在明显差异⁵）被观察到导致每个制度不同的过程定律。最终绘制了主曲线，可用于根据两个无量纲数来帮助预测研究的实验域中的最终泡沫体积。
