IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Unstructured simulation of thermal and shallow circulation flow using depth averaged easm model
Author : L.H. Xing , G.B. Huang ,and Min Yan
In order to alleviate the pollution of thermal discharge from a power plant, the layout of the intake and discharge modes needs to be optimized. For doing this, the main characteristics of thermal and shallow circulation flow would be well predicted, including flow pattern, flow field and temperature distribution. In view of economics, a fine and better unified depth-averaged turbulent model is developed to describe the complex shallow circulation flow. The recommended model is derived from an explicit algebraic Reynolds stress model and has the adaptability to arbitrary natural shore boundaries. The efficiency of the present numerical model is verified by a physical model concerning cold water intake and thermal water discharge synchronously. The numerical results are in good agreement with experimental data, including velocity, temperature, the stagnant points of circulation flow and the corresponding diversion point. In addition, the dissipated energy, turbulent kinetic energy and eddy viscosity of the thermal circulation flow are also studied and their distributions are reasonable.
