多相流cfd程序，用fortran实现，有多流体和dem计算功能，当然还有其它更多功能(MFiX is a general-purpose computer code developed at the National Energy Technology Laboratory (NETL) for describing the hydrodynamics, heat transfer and chemical reactions in fluid-solids systems. It has been used for describing bubbling and circulating fluidized beds and spouted beds. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. MFiX code is based on a generally accepted set of multiphase flow equations. The code is used as a "test-stand" for testing and developing multiphase flow constitutive equations.)

Gao-Collins粒径趋势模型是把粒径趋势矢量的平面分布图看成为一幅同时包含信息和噪声的图象, 从而用图象处理技术来提取平面二维粒径趋势矢量图象中所含的沉积物输运信息 。按照这种方法, 对于所考虑的海域可通过各采样点底质的粒度分析获得粒径参数的平面分布图式, 然后经粒径趋势分析获得沉积物输运图式。粒径趋势分析的第一步是在采样点网格上对每两个相邻的采样点进行比较, 找出所有的粒径趋势矢量。两个采样点是否/相邻0, 可用特征距离D cr 来衡量(D cr 通常为最大采样间距)。如果两采样点的实际间距小于D cr , 则判定为/相邻0, 否则判定为/不相邻0。第二步是用下式求出每个采样点的趋势矢量的和
