Abstract

The design of koi pond models using CFD software simulation is to determine the effect of pond geometry to the flow characteristic of water. The goal of this project is to design a pond without stagnant areas. A design guideline on how to build an optimize koi pond is revealed. A pond model is constructed in a few different geometry shapes using Ansys CFX 10.0 software with different parameters to study on how the flow will react with the change of these parameters. The listed parameters are pond depth, bottom contour, angle, radius and also the location of inlet (waterfall) and outlet (bottom drain) of the pond. All these are the possible parameters that may affect the flow characteristics of water in the pond. A 5 feet pond depth proves to be the most suitable depth for a koi pond. A bottom contour of 1 00 degrees is proven in the simulation to provide the self cleaning feature. Angle wider than 90 degrees and pond radius larger than 2 feet provides a smooth and better flow with no stagnation area.
