【 摘 要 】

A two-dimensional unsteady large eddy simulation model of a trapezoidal solar pond is carried out on the platform of Fluent17.2. On the basis of verifying the validity of the model, the characteristics of temperature change, velocity and vorticity distribution, and salt concentration change at the interface are analyzed. The result shows that the overall temperature of the solar pond increases over the running time, and the maximum temperature (314 K) appears in the lower convective zone after 10 days of operation. The velocity field and vorticity field are mainly distributed in the lower convective zone (LCZ), and the velocity remans at the order of 10-4 m/s. The salt concentration at the upper and lower interface decreases obviously under the influence of salt diffusion.
