The dynamics of the crown formation due to the impact of a drop onto a thin liquid film is of interest in fluid mechanics and engineering applications. The drop impact on liquid film has several significant applications, particularly in inkjet printing, coating, spraying, painting, and cooling pr...

Numerical simulations of the early instants of a plane two-dimensional drop impact on a pre-existing thin film of the same liquid are performed. The evolution of the phenomenon is computed by solving the Navier-Stokes equations by means of a Volume of Fluid (VOF) method. The analysis takes ...

Drop impact on thin film: Mixing, thickness variations, and ejections The impact of drops on a thin liquid film is a phenomenon encountered in industrial\napplications, but also of particular interest in nature. Examples include the growth of\nstalagmites in karstic caves, a case where the dr...
The impact and splash of liquid drops on solid substrates are ubiquitous in many important fields. However, previous studies have mainly focused on spherical drops while the non-spherical situations, such as raindrops, charged drops, oscillating drops, and drops affected by electromagnetic field, rema...
Numerical analysis of droplet impact onto liquid film Normal impingement of a single droplet on a thin liquid film is investigated numerically solving the axisymmetric Navier-Stokes equations. Gravity and visc... H Shetabivash,F Ommi,G Heidarinejad - 《Physics of Fluids》 被引量: 15发表: 2014年...
We elucidate the evolution of the entrained air in drop impact on a wide range of liquids, using ultrafast X-ray phase-contrast imaging. We elaborate the retraction mechanism of the entrapped air film in terms of liquid viscosity. We found the criterion for deciding if the entrapped air evolve...
Abstract This paper numerically analyzes the crown formation due to a plane two-dimensional drop impact onto a pre-existing film in a viscoelastic fluid. The finite volume method is applied to solve the governing equations, and the volume of fluid technique is utilized to track the liquid’s fr...
At the impact of a liquid droplet on a smooth surface heated above the liquid's boiling point, the droplet either immediately boils when it contacts the surface ("contact boiling"), or without any surface contact forms a Leidenfrost vapor layer towards the hot surface and bounces back ("gentl...
