| A computer program is developed in order to investigate the fluid flow and heat ransfer of a water body in a 2-D vertical rectangular coordinate. The specific purpose of this study is to obtain a physical insight of several fluid flow problems which occur in a lake and the water and wastewater treatment facility like a primary clarifier. The performance of computer program developed is successfully evaluated by the comparison of other two experimental and computational data in open literature : the first comparison is made against the numerical data associated with the cooling water discharge and the other is numerical and experimental works for the primary clarifier of Sarina City at Ontario. Further, the computer program is applied to investigate the feature of lake flow, say lake turnover, and 2-D vertical channel flow in terms of temperature, wind velocity and flow rate, etc. The computational results appear to be physically acceptable and consistent. The computer program developed in this study shows the possibility of the viable tool to figure out the flow characteristics of water reservoir. |
