【Abstract】 A model is presented to simulate the temperature rise of cooling water.In the model,control equations of cooling water are discretized on the base of curvilinear grids by using of the finite volume method and SIMPLE algorithm.At last,the model was used to simulate a meandering channel,and model results show the model can correctly reflect the movement rules of cooling water,which indicates this model is satisfactory in engineering practice.更多还原
