Designing bioinspired conical surfaces for water collection from condensation.

Area of Science:

• Surface science
• Fluid dynamics
• Environmental engineering

Background:

• Arid regions rely on fog and condensation for water.
• Conical and triangular patterns aid droplet transport via Laplace pressure gradients.
• Previous condensation research focused on flat surfaces, limiting practical application.

Purpose of the Study:
