It was found that the convection within the water droplet was proportional to the microwave power. In contrast, the frequency of oscillation was independent on the microwave power. These results on surface tension, oscillation and convection will provide important insights for designing microwave ...
This paper describes a lattice Boltzmann-based binary fluid model for inkjet printing. In this model, a time-dependent driving force is applied to actuate the droplet ejection. As a result, the actuation can be accurately controlled by adjusting the inte
(IIF) model to simulate droplet deformation.The computational results of the CSF model are in better agreement with analytical results.The CSF model also has better agreement in surface tension simulations than the IIF model.IIF can also be used to simulate surface tension.Howover,the parameters ...
The effect of droplet size on surface tension is given theoretical consideration with the help of results of the Gibbs thermodynamic theory of capillarity and of previous results of the author as to the sign and magnitude of superficial densities. It is concluded that surface tension can be expect...
3.1. Effects of surface tension on Wec The critical Weber number, Wec, has been used to distinguish the phenomena of splash, i.e., shoot one or several daughter droplets, as a liquid drop impacts upon a surface. Fig. 2 shows the impact patterns of different water drops impinging on paulo...

Comparisons with findings for sessile droplets are also discussed, pointing to additional effects of nanoparticles other than the non-equilibrium evaporation process. 展开 关键词: Nanofluids Surface tension Evaporating droplet Stefan’s formula DOI: 10.1016/j.ijheatmasstransfer.2011.02.016 被引量: 82 ...
Alternately, if the surface tension of the liquid is known, the maximum force of the meniscus can be used to calibrate the spring constant of the AFM cantilever. The contact angle of the liquid on the rod was calculated as the rod was inserted into the liquid droplet. Contact angle ...
This study builds upon prior research by exploring droplet oscillation dynamics for surface tension determination using a drop-on-demand high-temperature d
Critical surface tension (CST) is a measure of solid surface tension and is mainly determined by measuring the contact angle of a droplet on a target solid surface. The concept of CST makes it possible to determine solid surface tension without any unprovable assumptions such as the Fowkes hypot...
