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
flow. These eddy movements bring about mixing throughout the turbulent core. This process is often referred to as "eddy diffusion." The value of the eddy-mass diffusivity will be very much larger than the molecular diffusivity in the turbulent core.
2. Fluid dynamics
- In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid flows past stir bar. Thi
