摘要 在外界来流作用下,液滴在固体表面上呈现周期性振荡特性．利用数值方法模拟平板上二维液滴在气流剪切作用下的界面及内部流动特性,重构二维液滴内部流场,着重认识液滴内部速度分布和压力分布． A numerical somulation was conduted to investigate the inner flow in a oscillating liquid droplet. A 2-D model was proposed to describe the interfacial and inner flow of oscillating droplets with shear stress induced by outside air flow. The 2-D inner flow field was re-constructed to explore the liquid flow velocity and pressur profile and better understand the oscillation mechanisms.
