FLUID LEAVES: EFFECTS OF FLUID FLOW ON LEAF SHAPES AND FIBONACCI SERIES

Abstract

The liquid chain and other fluid phenomena, which resemble leaves of plants, are categorized as fluid leaves. Liquid chain happens when two liquid jets hit each other at an angle, or when the liquid jet flows on smooth surfaces. Liquid leaves are not just limited to fluid engineering, but also to biology. The literature shows that the liquid chain looks like leaves, but there are not many resources explaining the physics of the shape being in the form of a leaf. In this work, the author shows that liquid impacting different types of surfaces does form a leaf–like structure. The detailed theory on biology and liquid leaves is mentioned in the application section for better understanding of the scope of this study. This paper visualizes different types of leaves with changes in surface types, and it also reports a new property of fluids found from a simple experiment involving the droplet coalescence. It is remarkable to find that the fluid property is the reason for Fibonacci Series in the universe, including living and non-living things.
