Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.

In general, the design work with traditional measures is done by hand, which cannot meet the needs of the technology and manufacture. So the author has developed a CAD hydraulic design software fit for lower specific speed axial flow runner, which is easily operated by users.The main research work of this paper is as follows:1 Analyzing the main reason of axial flow power station cannot work well under littler volume of flow in some season and putting forward an improving scheme, pointing out the characters of design under abnormal factors.2 Combined with the development of the industry in our country, the abnormal hydraulic design method of propeller turbine is discussed based on present literature, data and experiment results.3 Guided by the design method of software engineering, a suit of hydraulic design software of Lower Specific Speed Axial Flow Runner is programmed by the object-oriented programming language Visual Basic and a straightforward, concise and standard Windows human-computer dialogue interface is designed for the system, which makes the operation of the system very convenient.4 ActiveX Automation technology is adopted as the interface with AutoCAD and the hydraulic drawings are edited, modified by AutoCAD until hydraulic model drawings according with the demand of engineering practice are output.5 To resolve practice problem, the author has designed a lower specific speed axial flow runner for Duowa Power Station through an example.

With the higher requirement of the low energy lost of hydrocyclone, especially single-level hydrocyclone inaccessible separation standard, industrialization requirements are carried out by series-parallel connection of multilevel hydrocyclone. Thus, the utilization of uniflow hydrocyclone becomes more and more abroad when the hydrocyclone changes its role from primary ultimate separation equipment to advance separation equipment.

Results show this new-inlet hydrocyclone has original sides on liquid spin-making and stabilize its flow field. Moreover this gradual contraction inlet may translate some pressure energy of liquid into kinetic energy and increase circumrotate speed. These play active actions on improving separation efficiency. Moreover, the uniflow hydrocyclone has the traits of big capacity, low pressure drop and a little low separation efficiency in contrast to the returned flow hydrocyclone. This hydrocyclone system has the higher separation property in contrast to the single-level hydrocyclone.
