Abstract:
By the non interposition flux reconstructed and limiter,one high-order transport model is constructed based on arbitrarily unstructured shallow flow model and finite volume method.The stability and non-oscillatory condition are analyzed,its scalar transported in the circle flow is simulation,which shows that this model is of high order and non oscillatory.At last,the model simulates the salt transport of the Oujiang estuary,and the results show shat the water levels,velocity and salt are agree ment with the measured ones.
