(Genetic Algorithm Based K-means algorithm, related program and algorithm description.)

应用背景This application is to focus on the numerical methods in Computational Fluid Mechanics, dealing with aeronautics, hydraulics, heat and mass transfer etc. We konw fluids have the ability to transport matter and its propertities as well as transmit force, therefore fluid mechanics is a subject that is particularly open to cross fertilization with other sciences and disciplines of engineering. The subject of fluid mechanics will be highly relevant in domains such as chemical,metallurgical, biological and ecological engineering.关键技术 SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algrithm is the principal numerical method to numerical simulate incompressible fluid flow, it can remove the difficults of fake pressure disturbance and neglecting specific pressure equation for incompressible fluid flow successful. The main thoughts and steps of SIMPLE algorithm are given in this application. The single-phase loc
