Abstract: A laterally-averaged tow-dimensional thermal-ice model for seasonal ice-covered reservoir is developed. In this model, two-dimensional flow and water temperature distributions are solved by the finite volume method with the k-ε turbulent model. Supercooling and frazil ice, and the formation of initial ice cover are considered. Thermal growth and decay of the ice cover is modeled by vertical heat transfer and heat exchanges at air-ice and ice-water interfaces. The model was applied to the 153 km-long Fengman Reservoir on Songhua River. Simulation result showed a good agreement with field data in both vertical water temperature distribution and ice thickness. Effects of inflow water temperature on thermodynamic behavior of ice and water in reservoir are discussed.
