Liquid properties are relevant for the understanding of fundamental and applied sciences. Among these properties, those that can be traced back and explained through the surface tension are particularly interesting to study and reconstruct in educational terms. Traditional educational treatment of surface tension is often obscure or too complex, sometimes superficial or completely neglected. The aim of the research here described is to discuss in detail a mesoscopic model of liquids and show quantitative results obtained by a computer simulation approach. Looking at the educational aspect, the main advantage of this approach is that it allows the student/teacher to control the simulation parameters and understand step by step how the physical quantities influence the investigated system. Some of the main properties of capillarity phenomena (meniscus formation, capillary rise, etc) are analysed through the simulation of a liquid in a tray with a capillary tube inside, where a value of surface tension is obtained.

液体性质与理解基础科学和应用科学有关。在这些性质中，那些可以通过表面张力追溯和解释的性质，在教育方面进行研究和重建特别有趣。表面张力的传统教育处理往往模糊不清或过于复杂，有时肤浅或完全被忽视。这里描述的研究的目的是详细讨论液体的介观模型，并显示通过计算机模拟方法获得的定量结果。从教育方面来看，这种方法的主要优点是它允许学生/教师控制模拟参数并逐步了解物理量如何影响所研究的系统。
