基于有限体积法求解二维欧拉方程，是流体问题的最基本求解方法(The finite volume method to solve two-dimensional Euler equation)

计算在不同湿度下，不同频率下，大气的衰减系数。(Calculation under different humidity, different frequencies, atmospheric attenuation coefficient.)

说明：  分数傅里叶变换程序，这个是二维分数阶傅里叶变化程序。(Fractional Fourier transform procedure, this is a two-dimensional fractional Fourier change process.)

本代码可以用于计算特征向量或者矩阵的相似度。(This code can be used to calculate the similarity of the feature vector or matrix.)

傅立叶变换的C语言实现，可在Turbo C以及Visual C++下实现。(Fourier Transform C language, in Turbo C and Visual C under.)

涡格法计算机翼的涡强，对不同剖面形状，拱度等进行了比较分析。并且与书籍上对比(Vortex lattice method the computer wing of the vortex is strong, the shape of different profiles, such as camber, a comparative analysis.)

说明：  FLUENT中离散相粒子追踪设置及相关计算，设计用户自定义相关内容(Discrete phase particle tracking in FLUENT)
