The numerical calculation of the complex hydraulic interaction between a cooling water discharge and an ambient current is described. The calculated flow patterns compare favorably with those observed in dye studies of a physical model. Results are presented for several values of the ambient current, showing several interesting features. At ambient velocities of 1 fps (0.3 m/s) the cooling water discharge is transported directly downstream. However, with an ambient current of 0.5 fps (0.2 m/s) or less, a large recirculating region develops, in which the discharge flow is reentrained in a circulatory flow pattern. When this occurs, the temperature drop along the discharge jet will be reduced sharply due to the increased temperature of the entrained fluid.
