The numerical analysis technology has been widely developed as an important tool in engineering design by a price cutting and rapid development of the CT(Computer Technology), especially the speed-up of Engineering Workstation (EWS) and Personal-Computer (PC). On the other hand, the advancement of Computational Fluid Dynamics (CFD) technologies are also remarkable, a variety of analytical new techniques and the turbulent flow models are proposed, and these techniques have come to be able to apply to complicated flow analysis. Recently, a lot of simulations which the separation and swirl are accompanied are announced one after another and the range of application has become wider. Moreover, computer graphics (CG) technology develops remarkably in recent years and this strong drafting tool is used to make an analytical result and the data processing result visual on the computer display in real time. In this paper, author introduces the cases where the present flow analysis technologies are applied to the design of hydraulic turbines and pump-turbines, and shows the reliability and the economy of the three dimensional flow analysis technology.
