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.

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.

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

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.

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.

Ballistic deposition onto inclined surfaces

Physical Review A, 1988
Simulations of ballistic deposition onto an inclined surface (deposition at non-normal incidence) have been carried out using two-dimensional lattice and off-lattice models and three-dimensional off-lattice models. For most of these models the relationship between the angle of incidence (\ensuremath{\theta}) and the angle of growth (\ensuremath{\varphi}

Flame spread on inclined surfaces

Fire Safety Journal, 1992
Abstract Experiments have been carried out to investigate the effect of slope on the rate of upward spread of flame over a combustible solid. There is a clear difference between the mechanisms of spread for thin and thick fuels. With the latter, a change in mechanisms is found to occur at an inclination of 15–20°.
