About Me
My name is Md Hedayetul Islam Chy, a third semester graduate student in the department of
Electrical and Electronic Engineering at the University of Chittagong. Currently, I'm working under the
supervision of Dr. Mohammed Arif Iftakher Mahmood. In my recent research, I am exploring natural surfaces
with the goal of designing anti-splashing surfaces that mimic natural structures.
In addition to this,
my research interests encompass a wide range of areas, including Computer Vision, Medical Image Analysis,
Wearable Electronics, Machine Learning, and Bio-Engineering.

"Natural surfaces have micro and nano structures that affect the splashing behavior of water droplets
falling on them. Synthetic surfaces mimicking this natural phenomenon have been previously reported. The
objective of our current work is to design such surfaces and fine tune the fluid splashing behavior using
three-dimensional(3D) simulation tools. We have designed and simulated splashing behavior on geometrically
patterned micro scale surfaces using the Volume of Fluid(VoF) method. Surfaces with micro scale pillars of
different heights, geometrical shapes, layouts as well as tip designs were simulated with the goal of
minimizing fluid splash. We found that certain pillar models produce less splashes than others. We have
further optimized array structures for fluid splashing diameter and velocity. Behavior at different
falling angles and fluid types are also investigated in multi-pillar models. The results indicate that a
non-uniform structured surface decreases the speed and energy of the falling droplet. We have reported
here three finalized designed models that are 35%, 63.5% and 69% effective in reducing splash compared to
a flat surface model."
