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

正整数x 的约数是能整除x 的正整数。正整数x 的约数个数记为div(x)。例如，1，2，5，10 都是正整数10 的约数，且div(10)=4。设a 和b 是2 个正整数，a≤b，找出a 和b之间约数个数最多的数x。 对于给定的2 个正整数a≤b，编程计算a 和b 之间约数个数最多的数。 数据输入 输入数据由文件名为input.txt的文本文件提供。文件的第1 行有2 个正整数a和b。 结果输出 程序运行结束时，若找到的a 和b 之间约数个数最多的数是x，将div(x)输出到文件output.txt中。 输入文件示例 输出文件示例 input.txt output.txt 1 36 9 -Positive integer x can be about a few of the positive integer x divisible. Positive integer x the approximate number recorded as the number of div (x). For example, 1,2,5,10 are about 10 positive integer number, and div (10) = 4. Set a and b are two positive integers, a ≤ b, to find a and b between about a few number of the largest number of x. For a given two positive integers a ≤ b, Programming calculated a and b between about a few number of the largest number. Data entry input data from the document text file named input.txt provide. File line 1 has two positive integers a and b. The results run the end of the output, if found between a and b of about a few number o

模拟退火算法(Simulated Annealing ， 简称SA)为求解传统方法难处理的TSP问题提供了一个有效的途径和通用框架， 并逐渐发展成一种迭代自适应启发式概率性搜索算法。用以求解不同的非线性问题； 对不可微甚至不连续的函数优化， SA 能以较大概率求得全局优化解； 具有较强的鲁棒性、全局收敛性、隐含并行性及广泛的适应性； 并且能处理不同类型的优化设计变量( 离散的、连续的和混合型的) ； 不需要任何的辅助信息， 对目标函数和约束函数没有任何要求。利用Metropolis 算法并适当地控制温度下降过程， 在优化问题中具有很强的竞争力， 本案例研究了基于模拟退火算法的TSP算法。

粒子群优化算法（PSO,particle swarm optimization）是计算智能领域，除了蚁群算法，鱼群算法之外的一种群体智能的优化算法。函数寻优是工程中经常遇到的问题，有些函数因为局部极小值点的存在，算法难以寻找到局部最优值。粒子群算法具有群体智能，全局寻优等优势，比较适合于函数寻优问题，本案例研究了基于粒子群算法的函数寻优算法。
