普蘭店灣水體交換數(shù)值模擬研究
[Abstract]:Using irregular triangular mesh and finite volume method, the numerical model of tidal current near Plantan Bay is established. On the basis of verifying the good mathematical model of tidal current, the dissolved conservative substance is used as tracer. The water exchange situation in Plantan Bay was numerically simulated, and the water exchange capacity of each region was studied by dividing Plantan Bay into six regions. The results show that the topography and geographical location of different areas in Plantan Bay vary greatly, and the plane distribution of water exchange capacity is not uniform. The fastest water exchange rate between the six sub-regions of Plantan Bay and outside of the bay is area A (at the mouth of the bay). After 10 days of continuous tidal action, the exchange rate of water reaches 45g. The slowest rate of water exchange was after 100 days in F area, the exchange rate of water was 14. The regional difference of water exchange control mechanism in Plantan Bay makes the water exchange rate of different areas in the Bay quite different.
