液滴撞击等温斜面的数值模拟

Numerical simulation of droplet striking on inclined isothermal surface

采用基于volume of fluid(VOF)方法的计算流体力学二维模型,在考虑表面张力及壁面黏附的情况下,研究水滴在撞击浸润性不同的倾斜表面的铺展过程。结果表明,不同的壁面润湿特性对液滴铺展的影响存在差异。计算所得结果与实验测量值相吻合,表明了VOF方法研究液滴碰撞的可行性。

Based on VOF,a two-dimensional computational dynamic model is adapted to study the spread characteristics of water droplet impinging on inclined surface with different wetting properties. The surface tension and the adherence are considered in this model. The results show that the spread process differ with the wetting properties. Agreements can be obtained from the computational results and experimental results, that proves it feasibility to research the droplet impinging process with VOF.
