Application of Computational Fluid Dynamic for Hydraulic Design

摘要

This paper studies the modem design methods of hydrauhc machinery by the use ot Computational Fluid Dynamic (CFD),the design method not only makes up the shortcomings of the traditional design method,but also can be compared on the computer which can save a lot of trial and testing costs in new product development.Form the velocity distribution and pressure distribution of turbine,the example shows,the simulated flow field using CFD software is in agreement with the actual condition and it basically meets the requirements of design.
