Description
Description
In this project, the effect of the contact angle on droplet collapse has been simulated, and the results have been investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The present model is designed in three dimensions using the SpaceClaim software. The length of the computational area is 5 mm, and its height is 3.5 mm.
This geometry is meshed in Ansys meshing software, and the total number of cells is 53440.
Also, due to the nature of the present problem, the transient solver has been used.
Droplet Methodology
In this project, a numerical simulation of droplet collapse with two different contact angles has been done using Ansys Fluent software.
The VOF model has been used to simulate and solve the two-phase flow field equations. This project investigates the collapse of water droplets on the wall at contact angles of 90 degrees and 120 degrees.
Moreover, the laminar viscous model is used to solve the fluid equations.
Droplet Conclusion
At the end of the solution process, two-dimensional contours related to water volume fraction, velocity, and pressure are obtained. This simulation investigates the behavior of water droplets in the two modes of contact angles of 90 and 120 degrees.
According to the animation, it is clear that when the contact angle is 120 degrees, the water drop has more resistance to the momentary turbulence created, But we see more scatter in the 90-degree angle mode. This phenomenon can be important when more drops are on the wall next to each other.

Edgar Carroll –
I’m fascinated by the effect of contact angle on droplet behavior. Can you elaborate on how the results of the 90 and 120-degree contact angles compare in terms of their impact on droplet spread and collapse dynamics?
MR CFD Support –
Certainly! Generally, a higher contact angle, like 120 degrees in this case, typically suggests a lower wettability and thus a droplet that is more resistant to spreading out on the surface. This can lead to a more spherical droplet shape upon impact. Conversely, a contact angle of 90 degrees indicates a neutral wettability, where the droplet may spread more upon impact and experience a higher degree of deformation and break-up. Therefore, in summary, you should expect to see the droplet with a 120-degree contact angle maintain a more compact form, while the droplet with a 90-degree contact angle spreads more before collapsing.

Can we also observe the effect on thermal properties if it was integrated, or is the focus entirely on mechanical properties with the contact angles?
MR CFD Support –
In this simulation, the focus is purely on the mechanical behavior, particularly the impact of different contact angles on droplet collapse, without integrating thermal properties. If thermal effects are to be included, additional setup and analysis would be required to account for heat transfer and possible phase change.
