文摘This paper deduces the variable-density equations and boundary conditions in the general curve coordinate system; A new 27-Point finite analytic discretization scheme is derived utilizing the superposition of the local analytic solutions of linearized two-dimensional convection-diffujon equations; The competent velocity formula of non-uniform bed sediment near the rivur boundary is also researched in the paper.
