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

一个汽车加满油后可行驶n公里，由起点a到起点b为m公里。汽车出发时加满了油，途中设有k个加油站，d1是第一个加油站距起点的距离，di是第i个加油站距其前一个加油站的距离。设计一个算法，求出加油方案，使得加油次数最少即可到达终点。解决策略  汽车是由起点向终点行驶，现在面对的问题是应该在那个加油站加油，可使旅途过程中加油次数最少。为了解决该问题，我们可以规定在油箱中的油不足以使汽车行驶到下一个加油站的前提下，才加一次加油，如此
