NUMERICAL FLUID FLOW ANALYSIS BY TWO-STEP EXPLICIT FINITE ELEMENT METHOD AND ITS APPLICATION TO DESIGNING

Civil engineering structures usually have complicated profiles, necessitating the use of Navier-Stokes equations in the analysis of flow fields. But in the case of complicated boundary conditions, motions in the viscous flow field governed by these equations cannot be explained easily using purely analytical procedures, except for some special cases. Wind tunnel and water tank tests must therefore be relied upon. To arrive at rational and economical designs, however, experimental investigations must be accompanied by theoretical analysis. For this purpose the author proposes the Two- Step Explicit Finite Element Method, a new analytical procedure for problems of complex flows with high Reynolds number and spillway. The applicability of the method is demonstrated with examples of complicated flow fields.
