Numerical Analysis of Mercury, Honey and Water Droplet Impact on Solid Surface Using OpenFOAM
摘要
Fluid droplet-surface impact phenomena have been very keen in industrial applications such as coating, fuel injection to engines, bio-printing, etc. This paper explores the numerical analysis of different fluid droplets, such as mercury, honey, and water droplets, using an open-source tool called OpenFOAM. A parametric study of the above droplets with varying contact angle and initial speed is studied to observe the collision and spreading phenomena of the above droplets. Simulations are performed under ideal conditions using laminar models with dynamic mesh conditions. A linear Gauss-Upwind scheme with a transient solver is used to perform the above simulations. From the numerical simulations, it is observed that the spreading of fluid droplets majorly depends on the contact angle and initial speed of the droplets for a given contact surface.
