Abstract

Abstract

The use of the mathematical models so far for three-dimensional flow has some limitations because of their simplifications.Many characteristics of the flow field can not be predicted by these models.In this paper the three dimensional elliptic governing equations are solved by finite-volume methods;the buoyancy extensions of the widely tested k-ε.model is adapted.The method is first applied to calculate the field of side discharge into open channel flow.The results are in good agreement with those of ref.[7].Then it is further used to the intake discharge problem which is of a typical layout in cooling-water projects,and the calculated results,which predict in detail the charactreistics of flow field,are reasonable.
