We examine the effect of stirring and mixing on the marine planktonic ecosystem. We present a number of models investigating the impact of patchiness in the population, diffusion, and fluid stirring on the spatial structure of the population and the overall production rates of the system. It is found that the heterogeneity of the system significantly affects the way the system behaves. The resp...

In order to further improve the mixing performance of device, structure agitator was optimized, and effects diameter pitch on solid-liquid suspension characteristics were analyzed by single factor method. Multiple reference frame (MRF), computational fluid dynamics, Euler multiphase flow model standard K- ε turbulence used investigate effect height from bottom particles in studied. The results ...
