Droplet Impact and Spreading on Inclined Surfaces

Langmuir, 2021
Introducing surface inclination in the case of droplet impact on solid substrates results in complicated dynamics post impact. The present work investigates the dynamics involved in the spreading phase of the droplet on inclined substrates. Experiments are conducted with water droplets impinging on inclined dry solid substrates with varying wettability

IMPACTING OF DROPLETS ON MOVING SURFACE AND INCLINED SURFACES [PDF]

Atomization and Sprays, 2020
Drop impact onto inclined and moving surfaces are seen in various applications, for example, inkjet printing, spray coating, or in agriculture; droplets impact on either the surface that is moving, inclined, or a combination of both. Studies in the literature have examined the phenomenon of drop impact in isolation, either for a moving surface, or an ...

Droplets on inclined rough surfaces

The European Physical Journal E, 2007
The behaviour of liquid droplets on inclined heterogeneous surfaces was simulated by the lattice-Boltzmann method using the Shan-Chen multiphase model. The effect of topography of the surface on the contact angle hysteresis was investigated. It is shown in particular, by using anisotropic rough surfaces, how surface topography and thereby the ...

Bubble Formation on Inclined Surfaces

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001
AbstractGas purging is used in metal casting processes to increase the product quality. We studied the influence of the surface inclination and the surface roughness on the bubble formation in experiments using water, air and teflon surfaces.

Droplet Splashing on an Inclined Surface

Physical Review Letters, 2019
Oblique droplet impacts onto a smooth surface at various inclination angles and at different ambient gas pressures were investigated using high-speed photography. It was found that the droplet splash can be entirely suppressed either by increasing the inclination angle or by reducing the ambient pressure.

A bouncing droplet on an inclined hydrophobic surface

Journal of Visualization, 2010
A trajectory of a water droplet of volume 0.4 μL impacting and bouncing on the hydrophobic surface (143°) inclined with 12° is presented. The photograph was taken with a 35 mm format digital SLR camera in a long-time exposure of 2.5 s illuminated with a couple of continuous point lighting.

Drop impact on inclined superhydrophobic surfaces

Journal of Colloid and Interface Science, 2016
This paper discusses the dynamic behavior of water drops impacting on inclined superhydrophobic surfaces. For a normal impact on a smooth hydrophobic surface, the spreading (or expansion) and retraction dynamics of an impacting drop varies from complete rebound to splashing depending on its Weber number, (We(d)), calculated using the impact speed and ...

Impact of droplets onto inclined surfaces

Journal of Colloid and Interface Science, 2005
Drop impacts onto dry walls and liquid films at low impact angles and low normal Weber numbers are experimentally investigated. Measurements were performed using a high spatial resolution CCD camera and short exposure times, yielding both qualitative and quantitative information about the impact.

Stick Insects Walking Along Inclined Surfaces

Integrative and Comparative Biology, 2002
In the experiments stick insects walk on an inclined substrate such that the legs of one side of the body point uphill and the legs of the other side point downhill. In this situation the vertical axis of the body is rotated against the inclination of the substrate as if to compensate for the effect of substrate inclination.
