Abstract

Numerical simulations of droplet interaction dynamics with a biphilic surface are performed using the multi-relaxation-time lattice Boltzmann method (MRT-LBM). The biphilic surface is modeled as a superhydrophilic circular region imposed within a superhydrophobic plane. The study is aimed at considering key aspects of droplet spreading upon an impact at the center of the superhydrophilic spot, droplet rebound, and formation of a residual droplet as the size of the superhydrophilic region is varied. Three characteristic interaction regimes are identified: droplet detachment, transitional regime, and droplet adhesion. Additionally, the velocity fields inside the droplet are analyzed throughout the entire interaction process.

双亲表面上入射液滴相互作用的动力学模拟

利用多松弛时间晶格玻尔兹曼方法（MRT-LBM）进行了液滴与双亲表面相互作用动力学的数值模拟。双亲表面被模拟成一个施加在超疏水平面内的超亲水圆形区域。该研究的目的是考虑液滴在超亲水点中心的撞击、液滴反弹以及随着超亲水区域大小的变化而形成残余液滴的关键方面。确定了三种典型的相互作用机制：液滴脱离、过渡机制和液滴粘附。此外，还分析了整个相互作用过程中液滴内部的速度场。
