Description
Description
In this project Contact Angle Effect on Friction Factor in Hydrophobic Surfaces is studied in ANSYS Fluent software .
The Contact Angle is a quantitative measurement of the wetting of a solid by a liquid. Every solid, liquid, and vapor system form a unique contact angle.
Hydrophobic and Hydrophilic surfaces repel and attract water and make more and less than 90 degree, respectively.
The geometry of the present model is three-dimensional and we model it using Design Modeler software. We do the meshing of the present model by ANSYS Meshing software. The mesh type is structured. Also, the element number is 250,047.
For a closer look, droplets with 125, 150 and 175 degree contact angles are modeled and their shear stress with the wall in different diagrams are compared.
Methodology: Contact Angle Effect on Friction
To simulate the multiphase treatment of the solution, VOF model is chosen. Also, the viscous model is assumed to be Laminar and the solver is transient.
Conclusion
At the end of the solution process, animations and two-dimensional contours of the volume friction of the domain are presented.
At first, a water droplet standing at the height of 20mm is patched into the domain, and its treatment is investigated under different contact angles. The literature says that the shear stress and friction factor will decrease by increasing the contact angle between water and surface.
As can be seen in the plots, the maximum amount of models is decreasing while the contact angle increases.

Juanita O’Conner –
I’ve always been curious about hydrophobic surfaces and the simulations look fascinating. Is it also possible to measure the difference in drag force on surfaces with varying contact angles using this simulation?
MR CFD Support –
Absolutely! The simulation allows for comparison of shear stress profiles for different contact angles, which directly relates to how smooth or repellent the surface is to water. . By analyzing the shear stress data, one can infer the drag forces experienced by the surfaces with differing hydrophobic properties.
Lavina Homenick –
The contact angles used in this simulation (125, 150 and 175 degrees) are much higher than the common 90 degrees threshold for hydrophobic surfaces. How does this increased contact angle affect the analysis you are presenting in this tutorial?
MR CFD Support –
With the increased contact angle of 125, 150, and 175 degrees, the simulation shows a more pronounced hydrophobic character of the surface, resulting in lower friction and shear stress as the contact angle increases. The tutorial presents how this enhanced hydrophobicity influences the fluid dynamics by displaying droplet behavior and the movement changes in contexts of friction and shear forces in comparison with more standard contact angles.

Mattie Lindgren –
I watched the tutorial and saw the droplets changing with different contact angles. However, can you explain how I can measure the contact angle of a surface in my lab?
MR CFD Support –
The contact angle of a surface in your lab can be measured using a method called sessile drop technique. It involves placing a small droplet of liquid on the surface and then using a camera to take a side-view photograph. After taking the photograph, you can analyze the image using software that’s capable of measuring the angle where the liquid and air interface meets the solid surface. There are also specialized instruments known as goniometers designed for this purpose which provide more precise measurements of the contact angle.
