摘要:

AbstractThis paper describes the use of the MacCormack explicit time‐spilitting scheme in the development of a two‐dimensional (in plan) hydraulic simulation model that solves the St. Venant equations. Various tests devised to assess the performance of the method have been performed and the results are reported.Finally, two industrial applications of the model are presented. The method has been found to be computationally efficient and warrants further developm

摘要:

AbstractSeparated flow past a circular cylinder is computed from two finite‐difference Navier–Stokes models. Stream functions are calculated using a successive‐over‐relaxation (SOR) procedure. Alternating‐direction‐implicil (ADI) and ‘upwind’ directional difference explicit (DDE) numerical schemes for solving the vorticity‐transport equation are compared. The ‘upwind’ differencing technique produces artificial viscosity which damps the wake and suppresses vortex shedding. It is shown to be unreliable and so the ADI ap

摘要:

AbstractAn efficient and versatile algebraic grid generation technique is presented for generating grid points in irregularly shaped and time‐varying spatial domains. The method presented is based on the ‘two‐boundary technique’ of Smith. The usefulness and the feasibility of the grid generation technique were demonstrated by (1) generating grid points inside one of the combustion chambers of a motored two‐dimensional rotary engine and (2) obtaining numerical solutions for the flow field inside one of those combustion

摘要:

AbstractA comparative study with a vertically integrated model and the multi‐level model has shown that the former can remain a good substitute for the latter in the prediction of sea‐surface elevation as long as the bottom friction coefficients in the vertically integrated models are properly specif
