Research on stochastic diffusion water quality model 隨機擴散水質模型研究
Using a dissolved conservative material as a tracer in the water , a three - dimension advection - diffusion water exchange numerical model was used to study the flushing time by discharge and the discharge dominated region of the yangtze estuary . the flushing time of the yangtze estuary is an important eigenvalue , which denotes the water environmental capability of estuary 然后應用以溶解態的保守性物質做為研究長江口水體交換的載體,建立了完全三維對流擴散型的長江口水體交換的數值模型,對長江口的水體交換時間做了一個整體的計算。
Using a dissolved conservative material as a tracer in the water , a three - dimension advection - diffusion water exchange numerical model was used to study the flushing time by discharge and the discharge dominated region of the yangtze estuary based on the successful simulation of flow field 在成功模擬長江口流場的基礎上,同時應用以溶解態的保守性物質做為長江口水體交換的載體,建立了三維對流擴散型的長江口水體交換的數值模型,對整個長江口的水體交換規律進行了研究。
