Ancient Dual Pond Sri Lanka

Project Overview:

Conducted a detailed 3D simulation and rendering of the ancient "Dual pond" (Kuttam Pokuna), showcasing its hydrologic engineering and design excellence.

Tools Used:

IC Measure for diagram scaling

AutoCAD for 2D drawings

SOLIDWORKS & AutoCAD for 3D structure

Ansys Fluid Fluent & Blender for textures and simulations

Historical Context:

Kuttam Pokuna, part of the Abayagiri monastic complex, dates back to the 6th-8th centuries. Its purpose, likely for monk bathing, reflects ancient engineering prowess.

Research Areas:

Identified design structure and ancient technologies.

Explored hydrology system and water flow management.

Investigated methods for maintaining water conditions.

Engineering Assumptions:

Algae/material removal in the first filtration step.

Different cross-sectional areas in drain lines for water level maintenance.

Hydrology Insights:

Varied pond sizes and characteristics.

Water supply from Anuradhapura tanks via underground pipelines.

Gravity-assisted water movement to Kuttam Pokuna.

Filtering System:

Water fountain filtering system with a drainage ditch.

Second phase purification using soil and sand drains.

Efficient silt removal for clear water entry.

Cooling System:

Dragon mouth entry for initial filtration and cooling.

Stone construction's natural cooling effect.

Underground drainage contributes to water cooling.

Possible use of algae plants for impurity absorption and additional cooling.

Conclusion:

Presenting a holistic view of Kuttam Pokuna's engineering marvels through a comprehensive 3D simulation.
