Abstract. An overall view of the flow over the fish gills is first described by using the active pump system and the passive ram ventilation. The concept of ram ventilation is introduced and its merits of reducing hydrodynamic drags and efficient e

In this slide, I will explain 2 kinds of problems of original flash mix. Structural and chemicals.
First, It has structural problems. As you can see the water flow direction, inlet locates downside and outlet locates upside.
Through this, we can know that axial
